1.1 Abstract
This project aims to provide real-life case as an introduction to building services system installed in a
multi-storey building. By introducing the common system used in the bigger volume of space with a variety of
users, this knowledge can be integrated into future design studio project to ensure a practical and technically
functional building design proposal.
The case study building that our group have chosen is the Malaysia International Trade and Exhibition Centre.
We are to analyse four system associated with building services which are active and passive fire protection
system, air-conditioning system, mechanical ventilation system and mechanical transportation system. A
thorough research was done prior to site visits. Two site visits were conducted to ensure complete data collection
such as information and pictures of building services components. The complete data is then analysed with
reference to Uniform Building By-Law 1984 (UBBL 1984), MS 1184 and MS 1525.
We are to produce a documentation and analytical report with a 5-minute video to present our findings about the
building services in MITEC. Pictures and video taken on site were used to visually portray the components of
each building services system with a comprehensives study describing the function and its importance.
All in all, we have learned a substantial amount of knowledge regarding to building services and its functions in
creating a safe environment for the occupants of the buildings. The site visit provides us an insight and a realistic
simulation of how building services are done in our local buildings and its implication towards a building design.

MALAYSIA INTERNATIONAL TRADE AND EXHIBITION CENTRE
Address : MITEC, 8, Jalan Dutamas 2, Kompleks Kerajaan, 50480 Kuala Lumpur, Wilayah Persekutuan
Kuala Lumpur
The brand new MITEC is the largest exhibition centre in Malaysia located at Jalan Dutamas, Kuala Lumpur. It
derives its unique shape from the rubber seed; a symbol of the Malaysia historical trade business. It is located in
Segambut, KL, next to Menara MATRADE. The architect firm for the project is RSP, one of the largest
architectural practices in the world with more than 1,300 professionals.
To ensure a perfect waterproofing under the decorative cladding system, Sika has developed a unique anchoring
system that is hot-air welded to the Sarnafil G-410 L Felt membrane. Simple, effective & efficient. The system was
applied over the 57,000 square meter roof surface to allow the astonishing finish expected by the architects and
owner. Kudos to Swissma Building Technologies Sdn Bhd and Sarnatec Sdn Bhd for a very professional work on
this exceptional structure.

FIRE
PROTECTION
SYSTEM
2.0 Fire Protection System
Fire protection system is the means to inhabit or mitigate the ignition, growth and spread of fire and its effects
through the built environment. The system serves the purpose to extinguish the fire, control the fire and provide
exposure protection to prevent domino effects. It can be classified into two types, which are active fire protection
system and passive fire protection system. Active fire protection system is the component of fire detection and
prevention which reacts to action or motion, while passive fire protection system is the component which seeks
to contain or slow down the spread of a fire. In general, the role of active fire protection within the fire
containment process is to detect, alert about, and seek to eliminate the fire hazard; passive fire protection, on the
other hand, is in place in case the active component fails in its objective, and is put in place as more of a failsafe
measure, rather than an active way to combat a fire hazard.
2.1 Active Fire Protection System
2.1.1 Literature Review
Active Fire Protection System requires a certain amount of motion and response in order to for it to work during
the event of fire. The system is either manually operated like a fire hydrant system or functioned automatically
like the water sprinkler and cannon system.The design of fire fighting systems should conform to specified
standards of Part VIII of Uniform Building By-Laws 2006 of Malaysia.
Fire Detection System
Detect the fire by detecting heat, smoke or
flames
Example : Smoke Detector
Fire Alarm System
Initiated by fire detection system and
triggers the following active system
Example : Fire Alarm Bell
Automatic Active System
Activated automatically to impede the spread of
fire and prevent damage to other area of the
buildings
Example : Water Sprinkler System

2.1.2 Water Based System
Water based system utilizes the inexpensive, non-toxic and readily available medium of water to discharge onto
flames through a variety of carriers. The properties of water being able to be stored at atmospheric pressure and
normal temperatures and to take the heat out of fire promptly make water better than any other recognized liquid
for fighting the majority of fire. There are 5 types of water based systems that present in the case study building.

2.1.2.1 Water Pump System
Water pump system is required to provide adequate pressure to meet the hydraulic demands of the case study
building, especially when water supply is provided from the water storage tank located on ground floor. There
are two main water tanks which are fire sprinkler - water cannon tank and hose reel - wet riser tank. Both of the
tanks have their respective sets of water pump to facilitate the operation. The system operates when the pressure
drops below a threshold. For instance, the fire sprinkler system pressure drops significantly when one or more
fire sprinklers are activated or alternatively when other firefighting connections are opened, causing a pressure
drop. In the building, the system mainly comprises of Jockey Pump, Duty Pump and Standby Pump.

2.1.2.1.1 Jockey Pump
Jockey pump, also known as a pressure-maintenance pump, is a
relatively small device that works together with the fire pump. It
is designed to keep the pressure in the system elevated to a
specific level when the system is not in use, so that the fire pump
doesn’t have to run all the time. This prevents the sprinklers
from going off unnecessarily. Moreover, since pipes are
susceptible to leakage over time, the water pressure inside them
tends to go down. As soon as the jockey pump senses this, it fills
them back up to normal pressure. Also, it can also help prevent
the system from damage when a fire happens and pressurized
water rushes into the pipes by regulating the pressure. It is
powered by electric supply and is connected directly to the fire
sprinkler water tank.

2.1.2.1.2 Duty Pump
If the pressure continues to drop under the threshold
during the operation of jockey pump,duty pump will
start working and give a high pressure supply. This is
to boost the pressure lost in the system. Duty pump in
MITEC is a horizontal split case pumps whereby it is
easy to be accessed to all of its working parts and has a
high efficiency in delivering water pressure.
2.1.2.1.3 Standby Pump
Standby pump is driven by a diesel engine. The pump
is controlled and starts automatically when a fall in
pressure occurs in piping exceeding three per cent of
the normal static pressure, and to stop automatically
when the normal pressure is re-established. Generally,
it operates during power supply failure.

2.1.2.2 Fire Sprinkler System
Fire sprinkler system acts as the crucial first-line of active fire protection. The system extinguishes or prevents
spreading of fire in its early stage, keeping the fire under control until the fire brigade arrives. Water extinguishes
the given area during fire, cools building structures and the surrounding area and at higher temperatures it
evaporates quickly, displacing oxygen and thus creates an inert atmosphere, which prevents the access of
oxidant, i.e. the atmospheric oxygen that is needed for combustion. It consists of distribution piping system that
is permanently attached to building structures, valve station and sprinkler heads that are firmly attached to the
distribution pipes in the protected area. Pipeline network together with sprinkler heads are connected to a water
source that provides adequate pressure.

2.1.2.1.1 Sprinkler Head
The system operates on wet pipe fire sprinkler system. The system employs fixed fire sprinkler heads and
sprinkler piping filled with pressurized water supplied from a dependable source at all times. Sprinkler heads are
equipped with a glass trigger filled with a glycerin-based liquid that expands with temperature. As the liquid
expands, it shatters its glass confines and activated the sprinkler head, water is then discharged immediately onto
the fire. The sprinkler heads are not all activated at once since each one of them is independent, thereby
minimizing water damage. Only sprinklers in the area of the fire that have reached the temperature required to
melt. The type of bulb used in the case study building is red liquid bulb.

2.1.2.1.4 Alarm Valve System
These sprinkler heads are attached to a reliable system of water pipes that are typically built into the walls or
ceiling. Beneath the sprinkler heads, a valve keeps the water from leaking out. When the sprinkler head is
triggered, the valve is opened and pressurized water is released from the pipe system. It’s important for water in
a fire sprinkler system to be pressurized. This allows the water to spray outward in an arc to more thoroughly
douse the fire and prevent it from reigniting.The alarm check valve is a key component of the wet pipe system. It
is designed to indicate when a sprinkler has operated as well as to provide a system check valve. The alarm
check valve serves as a check valve by holding the pressurized water above the clapper and preventing reverse
flow from the sprinkler piping. The valve initiates an alarm during a sustained flow of water by operating a water
motor alarm and alarm pressure switch. When it is installed with the water motor alarm, the system can provide
a local alarm even when electric power is lost.
Diagram 2.8 Both pendant and upright sprinkler head spray water in circle pattern
2.1.2.1.3 Upright Fire Sprinkler
An upright fire sprinklers spray water upward to a concave
deflector, producing a dome-shaped spray pattern. They are used
mostly in places where obstructions may block water spray
during a fire, and their height allows them to aim water around
possible obstacles. While they can't be hidden behind a cover
plate, system design can make upright models less of an eyesore.

System Mechanism
When a sprinkler (1) opens, the discharging water
lifts the alarm valve clapper (2) and flows through
the alarm port (3) to the retard chamber (4). When
the retard chamber is filled, water flows to the
water motor alarm (5) and the alarm pressure
switch (6) which signal an electric alarm bell.
To prevent false alarm due to variable water
supplies, the retard chamber (4) collects small
surges of water which flow through the alarm port
during pressure fluctuations.

2.1.2.3.2 System Operation
When fire occurs, the temperature rises due to the heat released from the fire
source. It will smart-scan immediately from horizontal and vertical directions
to determine the fire source exact location. Then, the central controller issues
instructions and sends alarm signals while starting the pump and opening
water valves. The fire artillery will aim at the fire source to put it off. Upon
detected that fire has been put off, the central controller will issue instructions
again to stop water jetting. In case of fire resurgence, the system will restart
again by repeating the same procedure. The fire artillery shoots water in the
form of cylindrical water column or water mist with long range, hence
providing wide range protection and powerful fire-fighting capability. Figure 2.17 Testing out water cannon

2.1.2.4.2 Wet Riser Landing Valve
Landing valves which are 65mm in diameter, connecting directly to
the wet riser main, serve as the main water supply to fire department
to the upper floors in MITEC whereas fire hydrants serve as the
water source on the ground level. It functions as a water tab whereby
it is to connect the canvas hose to access to the water source on the
upper levels for fire-fighting. The valves are equipped with a
coupling adapter which is directly screwed to the outlet and
stoppered with a cap.
2.1.2.4.1 Wet Riser Main and Air Vent
Wet fire mains are 150mm in diameter and are installed owing to the
pressures required to provide adequate fire-fighting water supplies at
the landing valves at upper floors and also to ensure that water is
immediately available at all floor levels. The provision of a built-in
water distribution system means that firefighters do not need to
create their own distribution system in order to fight a fire and
avoids the breaching of fire compartments by running hose lines
between them.
2.1.2.4.3 Canvas Hose and Hose Cradle
Hose Cradle and Canvas Hose of brand ‘Proflex’ is used in MITEC.
The canvas hose has a length of 30 metres and 65mm in diameter. It

2.1.2.7 Fire Hydrant System
A fire hydrant system is a water supply with a sufficient
pressure and flow delivered through pipes throughout a
building to strategically located network of valves for
fire-fighting purposes. Two way fire hydrant installation
in MITEC consists of a system of pipe work connected
directly to the water supply main to provide water to each
and every hydrant outlet and is intended to provide water
for the firemen to fight a fire. Where the water supply is
not reliable or inadequate, hydrant pumps are provided to
pressurize the fire mains. A firefighter connects a fire hose
to the fire hydrant and releases a valve to get water from
the water main. The fire hydrants are designed to allow
250 gallons of water to flow through the hydrant per
minute.

2.1.3 Non-Water Based System
Non-water fire suppression system is a fire suppression mechanism which works on putting the fire out without
using water-based agents. A common belief among the people is that the best way to fight fire is by using water.
But that is not the case, as not all fires can be dozed out using water. There are many cases where a standard
water-based fire protection system cannot and will not protect the building in the event of a fire. For instances
where you are fighting electrical fires, certain chemicals, metals, or flammable materials less dense than water
you need a specialty system to extinguish fires. In fact, most of the time water can cause more damage than
damage-controlling.
2.1.3.1 Fire Suppression System
Fire suppression system in MITEC is designed to protect a specific hazard and may be used to supplement the
active fire protection system by providing protection in the fire risk areas. To ensure proper fire protection, the
extinguishing agent compatibility with the protected hazard is concerned. The system functions to protect a
specific hazard when water is not a key suppression agent. This article will review some of the basic concepts of
three of these types of alternative fire suppression systems; wet chemical, dry chemical, and foam suppression
systems.
Fire Protection System
Building Services
Active Fire Protection System
Page 24 Malaysia International Trade
And Exhibition Centre
Fire Suppression System
The system consists of dry chemical such as
phosphate compound monoammonium phosphate.
The dry chemical extinguishes the fire by
interrupting the chemical reaction and cutting out
the oxygen source.
Example :
ABC Dry Powder Fire Extinguisher
Dry Chemical System Gas System
The system are stored as liquid, with nitrogen used
to pressurise it. Upon releasing the chemical agent,
chemical reacts with the fire and extinguishes it. It
is suited to data rooms and switch rooms in
MITEC.
Example :
Carbon Dioxide Fire Extinguisher
Carbon Dioxide Suppression System
2.1.3.1.1 ABC Dry Powder Fire Extinguisher
The ABC Dry Powder Fire Extinguisher can be seen in most of the
place in MITEC. It is a portable fire extinguisher which can take down
all the major kinds of fires though it specially tackles Class A, B and C
fires. The dry chemical in the units is monoammonium phosphate.
When the ammonium phosphate and aluminum sulfate particles are
ejected with massive force from the extinguisher, they fuse together to
form an airtight barrier that completely chokes off the oxygen from a
fire. The powder chemical works differently to extinguish the various
fires. It chemically insulates a Class A fire, smothers and breaks the
chain reaction for a Class B fire and will not conduct electricity back
to the operator in a Class C fire. However it is not recommended to be
used in enclosed spaces. This is because the powder can be easily
inhaled, and also the residue is very difficult to clean up after.

2.1.3.1.2 Carbon Dioxide Fire Extinguisher
Carbon dioxide fire extinguisher types smothers the fire by displacing
oxygen in the air but do not leave any substances unlike the other fire
extinguishers. It is particularly useful for offices and computer server
rooms in MITEC where electrical fires may likely to occur. They also
put out Class B fires (flammable liquids, such as paint and petroleum).
It suffocates fires by displacing the oxygen the fire needs to burn. It is
placed near to the source of the fire risk areas and the fire exits in
MITEC.

2.1.3.1.3 Carbon Dioxide Suppression System
Carbon dioxide (CO2) is a colorless, odorless, and chemically inert gas that is both readily available and
electrically non-conductive that leaves no residue behind. This means any sensitive equipment that is in the
protected space is not damaged by the CO2, which reduces downtime and costs. Once the CO2 has dispersed to
safe levels from the protected space, personnel can access any damage from the fire or smoke and quickly get
back to work with no cleanup needed. It extinguishes fire primarily by lowering the level of oxygen that supports
combustion. This mechanism of fire suppression is highly effective, requiring minimal clean-up and is used in
normally unoccupied hazard locations or otherwise avoided by personnel when discharged. In MITEC, each
electrical room has an carbon dioxide suppression system.

Portable extinguisher shall be provided in accordance with the relevant codes of practice and shall
be sited in prominent positions on exit routes to be visible from all directions and similar
extinguishers in a building shall be of the same method of operation.
Summary (Fire Extinguisher) :
The fire extinguishers system in MITEC meets the UBBL 1984 requirements listed under Section 227, (3). The
fire extinguishers are strategically placed at many locations to be easily accessible by users in the building
during the event of fire.
System Operation
A carbon dioxide fire suppression system eliminates the oxygen to
suppress the fire. The system is equipped with a smoke and heat
detector which will trigger the alarm system and send signal to the fire
control room through the fire control panel upon detecting smoke and
temperature rise. It then releases the carbon dioxide agent into the space
it is protecting. After 30 seconds, all the gas inside will be discharged
through piping, leaving only carbon dioxide inside with the fire curtain
opened and smoke damper closed. The drop in oxygen level quickly
causes the fire to be suppressed or extinguished. On the control panel
outside, if green light lights up, it means that personnel is free to enter
the room whereas if the red light lights up, it means that the carbon
dioxide agent is being discharged and the room cannot be entered.

2.1.3.2 Fireman Switch
A fireman switch is a specialized switch that allows fire brigades to disconnect power immediately from high
voltage devices that may impose danger in the event of emergency. The enclosure of the switch is made of non
flammable material and painted red to be spotted easily by fire brigades. Fire brigade uses an insulated rod
which is also known as the ‘Fireman’s Axe’ to pull the handle to locking it at ‘O’ position to isolate the utility
supply to the building. To reset, a ‘two hands grip’ must be used. In MITEC, it is located at every level at the
escape corridor and not more than 2.75 metres from the ground.

2.1.5 Fire Detection System
A Fire Detection System (FDS) is an alarm system that receives data on, assesses and then responds to event
reported by various detector which usually consists of smoke detector, heat detector and damper which play a
significant role in protecting the the safety of emergency personnel. Fire Detection System are permanently
installed manual and automatic systems to detect fires at the earliest stage, warn those affected and quickly
inform the relevant emergency service. A properly installed and maintained Fire Detection System commit to
save lives and largely reduces building property damage. To be useful, fire detection system should work with
fire alarm system to become a life-safety system which ensure a rapid detection of fire.

The purpose of an automatic Fire Detection System is to detect an occurrence, alert the control panel and proper
authorities, and notify the occupants to take action. All parts of MITEC to be monitored are equipped with a
network of electric cables and automatic or non-automatic detectors. These detectors are operated either
manually or triggered automatically by heat, visible or invisible smoke, or flames. From here, system are all
connected and communicate both with each other with a central control monitoring location. Only the detectors
in the immediate vicinity of the fire are activated, sending a report to the fire detection control panel. The
interconnectivity allows the control personnel to identify the location of “address” where the initial detection
occurred. Information detected will be directed to emergency response team immediately for the fire rescue
operation. Once the fire has been extinguished, the system can be made operational again quickly and simply.
Diagram 2.15 Overall layout of Fire Detection System
2.1.5.2 Smoke Detector
Smoke detector serve as an indicator for the occurrence of fire which plays a crucial role in Fire Detection
System. As the first component which can react to the fire, detector will transfer signal to fire control panel in
fire control room to activates the alarm system. In MITEC, there are generally two types of smoke detectors
which is ionization smoke detector and photoelectric smoke detector.
Fire Protection System
Building Services
Active Fire Protection System
Page 31 Malaysia International Trade
And Exhibition Centre
Figure 2.50 Smoke Detector in Mega Exhibition Hall Figure 2.51 Smoke Detector in Control Room
The smoke detector provided in Mega Exhibition Hall
are mostly ionization smoke detector which generally
more sensitive and responsive to flaming fires. This
type of smoke detector sensitive at sending small
particles, which tend to be produced in greater
amount by hot, flaming fires, that are consuming
combustible materials rapidly and may spread
quickly. In the ionization smoke detector, if the
smoke particle enters the chamber of the ionization
detector it will reduce air ionization inside the
chamber of the ionization detector and triggers the
alarm to alert the building occupants.
The photoelectric smoke detector which uses a light
beam to help detect the presence of smoke. This
alarm types are more effective at sounding when a
fire originates from a smoldering source. Smoldering
fires may fill a room with dangerous gases before a
fire ever erupts. In a result, it is more suitable to be
implied in small room which smoke could be
accumulate in a short time of period. The presence of
suspended smoke particles in the chamber scatters the
light beam. This scattered light is detected by the light
sensitive sensor which sets off the alarm before the
smouldering fires bursting into flame.

2.1.5.3 Heat Detector
Heat Detector is a fire alarm device which designed to respond with sudden thermal changes or high temperature
from fire hazards around the installation area. Heat detector usually has a lower false alarm rate but it is slower
than smoke detector in detecting fires. In general, there are two types of heat detectors which are fixed
temperature heat detector and rate-of-rise heat detector.
Fixed Temperature Heat Detector:
Operate when the ambient temperature increases sufficiently to predetermined level where the heat detector will
operate. The heat is accumulated at the sensitive element due to a thermal lag. This causes the temperature of the
device to reach its operating temperature a while after the surrounding air temperature exceeds the device
temperature. When this happens, the detector is activated and an alarm is sounded.
Rate-of-rise Heat Detector (ROR):
ROR heat detectors may not respond to slowly developing fires. In order to detect slowly developing fires,
usually a fixed temperature element is added to the ROR detector which will be activated when the element
reaches the pre-set threshold temperature then triggered the alarm system.

2.1.4 Fire Alarm System
A fire alarm system has a number of devices working together to detect and warn people through visual and
audio appliances when smoke, fire, carbon monoxide or other emergencies are present. These alarms may be
activated automatically from smoke detectors, and heat detectors or may also be activated via manual fire alarm
activation devices such as manual call points or pull stations.
2.1.4.1 Fire Alarm Control Panel
A fire alarm control panel (FACP), fire alarm control unit (FACU), or simply fire alarm panel is the controlling
component of a fire alarm system. The panel receives information from devices designed to detect and report
fires, monitors their operational integrity and provides for automatic control of equipment, and transmission of
information necessary to prepare the facility for fire based on a predetermined sequence. The panel may also
supply electrical energy to operate any associated initiating device, notification appliance, control, transmitter, or
relay. There are four basic types of panels: coded panels, conventional panels, addressable panels, and multiplex
systems.

2.1.4.1 Fire Alarm Bell
A fire alarm is an electronic sounder or a bell. The alarm makes a loud, high pitched sound to notify people that
there is a fire in the building. Fire alarms may be activated automatically from smoke detectors, and heat
detectors. When a fire occur, the smoke detector and heat detector will send a signal to the fire alarm control
panel to activate the alarm bell. In MITEC, the alarm bells are installed at escape corridor and car park area. It
provides alert to the occupants in the building and detailed information as to the location of the fire occurred to
meet the needs of firefighting and detection system with central control equipment.

2.1.4.2 Manual Call Point
A manual call point is a device which enables personnel to raise an alarm in the event of a fire incident by
pressing a frangible element to activate the alarm system. A fire alarm call point should also be spaced so that
one may always be found within a maximum distance of 30m apart. The manual call points are located nearby
the exits and doorways for the occupants of the building to break the glass therefore a warning signal will then
send to the fire alarm control panel. In MITEC, manual call point were installed at a height of 1.4m above floor
level at easily accessible and conspicuous positions. This includes on exit routes, at the entry floor landing of
staircases and at all exits to the open air. It is a quick means for a person who does not have access privileges to
certain information to gain access when necessary. It is intended to specifically cover emergency cases and the
switch is used to cut electric circuit immediately. User authentication system is used to control and monitor
access to sensitive data. It is designed to preserve security by restricting access.

2.2 Passive Fire Protection System
2.2.1 Literature Review
Passive Fire Protection System (PFP) is a group of systems that compartmentalize a building through the use of
fire-resistance rated walls, doors and floors. Compartmentalizing building into smaller sections helps to contain
or delay the spread of fire and smoke from the room of fire origin to the other building spaces through fire
compartmentation. PFP attempts to limit the amount of damage done to a building and provides more time
safeguarding building occupants for evacuation. PFP systems must comply with the associated Listing and
approval use which compliance to Part VII of Uniform Building By-Laws 2006 of Malaysia in order to provide
the effectiveness expected by building codes.

2.2.3.3 Fire Containment
Fire containment systems are designed to isolate affected areas of fire origin by preventing smoke and heat and
ensuring small fires are not allowed to escalate into the full-scale blazes. Even if the fire is relatively small and
contained, the spread of smoke can cause some serious problems in the long-term, even to remote and otherwise
unaffected parts of a building.
When smoke cools, it drops, which can cause a building to become smoke logged. But when the fire and the
smoke is contained, it’s not allowed to cool, so it remains relatively buoyant. This can boost the efficiency of
smoke extractors and other ventilation systems.
2.2.3.3.1 Fire Rated Door
A fire door is one of the device of Passive Fire Protection system. It is fire-resistant and to reduce the spread of
fire and smoke between a separate compartments of a structure and to enable safe egress from a building. The
fire rated door are able to contain fire in a specific area for 2 hours.
In MITEC, these doors can be found at the emergency fire exits, control rooms, loading bay and more. The
components of the fire door consists of overhead door closer, fire resistant glazing, security devices and signages
as indication.

Summary (Fire Rated Door) :
The fire rated doors in MITEC has appropriate FRP of 2 hours that are located as openings of compartment
walls. These doors also complies with the requirement of having automatic closing function. For security
purposes, the doors are only accessible for employees of MITEC. Therefore, it is difficult for public to access
these areas. However during an emergency, a break glass is available right next to the door for access. In
conclusion, MITEC fire rated doors have complied with the requirements of UBBL stated above
2.2.3.3.2 Fire Rated Floor
Fire rated floor is a slab of a building that is fire resistance. Reinforced concrete structures with complex inner
geometry under the effect of high temperature considering void former materials. The materials has the highest
fire resistance classification and non-combustible. Slow rate of heat transfer while having structural integrity
Concrete’s inherent material properties, it can be used to minimise fire risk for the lowest initial cost while
requiring the least in terms of ongoing maintenance. Other materials rely on fire protection, fire safety
engineering or rate of loss of combustion. This reliance on fire protection, fire safety engineering and rate of
combustion makes them unforgiving of workmanship errors, future changes as simple as changing light fittings,
compliance with management procedures and human behaviour.
In MITEC, reinforced concrete were widely used in constructing the floor in order to achieve fire resistance of
the building

2.2.3.3.3 Fire Rated Wall
A fire-rated wall is a feature of a building’s passive fire protection system that has been checked and certified
by the proper regulatory agency. There are two basic types of fire-rated walls: true firewalls and fire barrier
walls. The first is a structurally stable wall that also is certified to prevent fire from spreading from one side of
a building to the other. Fire barrier walls, on the other hand, provide fire-rated protection while not being
structurally sound.
A fire barrier wall are interior walls that extend from the floor‐to‐floor or floor‐to‐roof, including concealed and
interstitial spaces. They are designed to sub‐divide portions of the building, and can be supported by structures,
such as roofs, columns or floors. All support structures should have a fire-resistant rating no less than that of the
fire barrier they support. Fire barriers restrict the initial flow of heat within the area of origin, which provides
building occupants with adequate time to evacuate to safe areas. These walls will typically have a 2 to 3‐hour
fire‐resistance rating.
In MITEC, a fire barrier wall are used with a material of reinforced concrete to provide fire resistance to the
space in the building.

materials, coatings, and systems used to prevent or
delay fire-induced temperature rise in structural
members in buildings. Structural fire protection for
walls, columns, and floors can be provided in varied
forms.
In MITEC, the building is structured utilising
reinforced concrete structure. However, masonry

Fire fighting access are routes used by firefighters to access the building to perform fire rescues. Vehicular
access to the exterior of a building is needed to enable high reach appliances, such as turntable ladders and
hydraulic platforms, to be used and to enable pumping appliances to supply water and equipment for fire
fighting and rescue activities.The requirements of accessway shall have minimum distance of width and terrain
between the apparatus access and the building ; how easily can they enter the building; building’s interior layout
and vertical access; and, the time taken for firefighters to locate the fire protection features and utilities.
2.2.4.1 Fire Engine Access
Fire engine access is the access for a vehicle designed primarily for firefighting operations. The access
arrangements increase with building size and height. Engine access provision, access from a public road should
be provided to assist fire and rescue personnel in their rescue and fire-fighting operations. Whilst the access will
depend to some extent on the vehicles and equipment used, assistance may be provided from adjoining fire and
rescue services when the need arises. For this reason, the more demanding guidance for high reach appliances
may be recommended by the fire and rescue service. This may have a significant impact on planning and a
feasibility study may be appropriate. In MITEC, firefighting engine access were provided from the main
vehicular road to the loading bay where the present of fire-fighting shafts are located at.

(Uniform Building By-Law, 2006, pp. 18, 19) (Original work published in 1984)
In the MITEC building, majority of the
building is air-conditioned by the chilled
water central air-conditioning system . It
comprises of centralized duct system,
consisting an air handling unit, air supply
system , air return duct and grilled that
circulate warm air from furnace cooled
air to spaces. The warm air from the
spaces is then returned back to the
system to be cooled down again.
3.3.1.1 Cooling Tower and Water Tank
Cooling towers are heat rejection device that are used to transfer heat to the atmosphere through the cooling of a
water stream to a lower temperature. An HVAC cooling tower is used to dispose of unwanted heat from chiller.
In MITEC, one chiller is paired with one cooling tower. Therefore, there are 6 cooling towers in MITEC .
Air-conditioning make up tank is located at the rooftop, usually near the cooling towers. As for MITEC, cooling
towers and water tanks are located both at the rooftop next to each other. Water tanks are to replenish the amount
of water in the condenser water systems in case there is any water loss due to cooling tower operation or
maintenance.
3.3.1.2 Chiller Plant Room
The chiller plant room comprises of all the important components of the chilled water air-conditioning plant.
These include the compressor, condenser, thermostatic expansion valve and the evaporator or the chiller. The
compressor is of open type and can be driven by the motor directly or by the belt via pulley arrangement
connected to the motor. It is cooled by the water just like the automotive engine.

Fan Coil Unit is a device consisting of a cooling heat exchanger or coil and a fan. It is a part of the HVAC
system found in residential, commercial and industrial buildings. FCU is used to control the temperature in the
space where it is installed, or served multiple spaces. While the AHU is used to ventilate the entire building , the
FCU are used in smaller places like the smaller halls and offices.
Conditioned air from FCU is supplied to the spaces by the ductwork system. The air supply travels through the
ductwork and is then distributed and discharged into the space by air diffusers. Then the circulated air is once
again collected by the return air inlet and returns back to the FCU to be cooled again..

The split air-conditioning system connect one indoor unit to an outdoor unit with evaporator, condenser and
compressor.
The indoor unit draws power from outdoor unit by a series of wires. The wire connect to its corresponding
terminal located at the electrical panel of the outdoor unit. A copper tube is connected parallel along the wire that
contains the gas from outdoor unit to indoor unit. Drain pipes are installed at the corner below the indoor unit to
remove the water easily. Cooling fan inside the indoor unit sucks the air from room and it is passed over the
cooling coil and the filter due to the temperature of the air reduces and all dirt is removed.
3.3.2.1 Indoor Unit
In MITEC the indoor units are installed in the fire control room on the basement floor as well as in the offices
and meeting rooms on the 2nd floor. This air-conditioning will not be constantly used in the offices , as it is only
a backup when the main system is down or used on weekends when only a few workers come to work.
3.3.2.2 Outdoor Unit
The outdoor units in MITEC are installed right outside of the offices and control room. Thus, most of the rooms

4.1 Literature Review
Ventilation plays a vital role in building to remove the stale air and replace it with fresh air from an external
environment.Ventilation system can be classified into two categories, natural ventilation and mechanical
ventilation. Both system had implemented in the building design as the need suited to the nature of building. In
mechanical ventilation system, components such as fan, filter, ductwork, dampers, grille and diffusers are used to
expel the stale air, working as a makeup air supply to enhance indoor quality. Mechanical ventilation can be
spotted usually in enclosed spaces that require good airflow.
Importance of mechanical ventilation system:
● Preservation of oxygen content and removal of carbon dioxide
● Control of humidity levels
● Prevention of heat concentrations from machinery, lighting and people
● Solution for unreliable natural ventilation system
● Reduce accumulation of moisture, dust, bacteria and smoke
● Dilution and disposal of contaminants.
There are various types of ventilation methods each serving different purposes and mechanical ventilation are
often used when natural ventilation is insufficient. There are 3 types of mechanical ventilation system:
● Supply system
● Extract system
● Balanced / Combined system
4.2 Components of Mechanical Ventilation System
4.2.1 Mechanical Fans
Fan is an important component of a mechanical ventilation system
which is used to create air movement. It provides a function of
removing hot, heat and polluted air. The mechanical fan consists of
a rotating arrangement of vanes or blades that aids in capturing
contaminants by carrying them to the air cleaning devices through
duct system. It brings in outdoor air for comfort ventilation or
convection cooling of buildings at night as well as provide constant
indoor circulation. There are mainly three types of fan, which are
propeller fan, axial fan and centrifugal fan as shown in the figures
below.

4.2.1.1.1 Propeller Exhaust Wall Fan
The purpose of propeller exhaust fan is for free air discharge. Commonly used without ducting but have the
ability of removing air. Propeller exhaust wall fans are found in utilities room such as lift motor room and
electric room to remove the heat produced by the machine. They are also found in rooms with high humidity and
odour such as the janitor room, help in avoiding accumulation of bad odour and maintain the standard humid
level within the room.
4.2.1.1.2 Induced Jet Fan
Jet fans are also known as impulse or induction fans. It is used to support the natural flow between the supply air
and extract air zones. They provide motion in regions with low air speeds, thus guaranteeing the daily ventilation
requirement for all areas. The induced jet fans used in MITEC are manufactured by Kruger and can be found at
the basement car park. Jet fans are only installed at particular points thus take up lesser ceiling area.

4.2.1.1.3 Centrifugal Fan
The centrifugal fan used in MITEC is a product manufactured by Kruger. It is a singlet inlet centrifugal fan with
forward wheels. This type of centrifugal fan has a frame fitted on both sides of the fan which gives better
strength and rigidity and allows mounting in four different orientation. Centrifugal fans operates against high
resistance by centrifugal forces generated by rotating disks and blades with aerodynamic properties.
4.2.2 Filter
Air filters are used in ventilation system for protection against impurities which may cause irregular operation of
the entire system or damage in its individual components. It is a part of component which composed of fibrous
or porous material that functioned as improving air quality. It is usually installed right behind the inlet grille.

4.2.2.1 Case Study of Air Filters in MITEC
In MITEC, linear grilles were commonly used in mechanical ventilation systems. The filters are installed behind
these grilles, functioned to remove impurities with as low as possible obstruction to the air flow and prevent
small particles such as dusts from entering the system which may obstruct and causes mechanical failure to the
system.
4.2.3 Ductwork
The ductwork system acts as air carriers to deliver air from one space to another. The needed airflow include
supply air, return air and exhaust air. The ducts are usually made of non-combustible materials such as sheet
material. They are usually rectangular and round in cross section.
4.2.3.1 Case Study of Ductworks in MITEC
The ductwork for mechanical ventilation system in MITEC is galvanized ductwork. They are rigid ductworks
which are rectangular in cross section and are found in the car park basement and machinery rooms as it can
withstand high air pressure since difference in pressure between outside atmosphere and inside ductwork might
affect its shape and safety. Rectangular duct is also used because it is easier to connect fan coil to main duct and
take up less height.

4.2.3.1.1 Combined use of ductwork with mechanical air conditioning
In the halls of MITEC, both air-conditioning system and mechanical ventilation system are connected to the
same main ductwork. Free cooling is used in MITEC, allowing fresh cool outside air into the HVAC system as
first stage cooling. In normal days, the damper will be drive open to bring in fresh outside air, helps in cooling
the house without running the compressor thus reduces the energy consumption. When there is a case of fire, the
barometric relief damper installed in the return duct will be activated and the smoke will be sucked into the attic
thus able to prevent the accumulation of smoke in the area.

4.2.4.1 Fire Damper
Fire dampers are required by all building codes to maintain the required fire resistance ratings of walls,
partitions, barriers and floors when they are penetrated by air ducts or other air transfer openings. Combination
of fire and smoke dampers are found in the halls and electric supply room in MITEC. When there is a rise in
temperature up to 165 Fahrenheit, the thermal sensor will detect the heat and the damper will be closed
automatically to prevent the spreading of smoke and fire. The damper used in the electric supply room is used to
prevent spreading of CO2 gas when the carbon dioxide suppression system is activated. The type of damper used
in MITEC is static fire and smoke damper since it is installed in horizontal barriers.
4.2.4.2 Pressure Relief Damper
This type of damper is found
used at every enclosed unit
staircase at MITEC. It acts as a
pressure relief damper which
helps to reduce the pressure
created by the supply ventilated
staircase pressurization system.

4.3 Types of Mechanical Ventilation System
4.3.1 Supply Ventilation system (Mechanical Inlet and Natural Extract)
4.3.1.1 Overview
Supply ventilation system applies the concept of
mechanical inlet and natural extract. It works by
pressurizing the building. Fresh air is drawn in
by a mechanical fan and is distributed to many
rooms forcing the stale air out through natural
extract exit such as windows or door gaps by
using a fan and duct system. This continuous
supply system allows occupant to have better
control of the air that move into the building
through filter option. The constant
pressurization of inlet air creates a positive
pressure which prevent outside contaminants
from entering thus it is suitable to be used in a
polluted and noisy environment.
4.3.1.2 Case Study of Supply Ventilation System in MITEC
The building incorporates supply systems in enclosed staircase pressurization system and lift lobby
pressurization system. Both work together to provide a smoke-free escape route in case of fire in the building. It
will also be a useful smok-free route for the firefighter to carry out firefighting operation.
4.3.1.2.1 Staircase Pressurisation System
One of the most hazardous situations that can be faced in a building is smoke. While fires themselves are often
damaging, it is the smoke that can cause the most injuries. In order to protect a building’s occupants, as well as
furnishings and equipment, a smoke control system is needed to control the flow of smoke and keeps smoke
from spreading throughout the building and gives the building’s occupants a clear evacuation route.
Building Services
Literature Review
Page 108 Malaysia International Trade
And Exhibition Centre
Diagram 4.5 Operation of supply ventilation
The primary means of controlling smoke movement is by creating air pressure differences between smoke
control zones. In pressurization, air is injected from the pressurization system located at the rooftop into the
protected escape routes, which include the emergency escape staircase. Higher pressure is established inside the
staircase than in adjacent part of the building. In this way, air moves into the smoke zone from the adjacent areas
and smoke is prevented from dispersing throughout the building.

4.3.1.2.2 Lift lobby pressurisation system
The use of a pressurised system in the lift lobby is to ensure it to be smoke-free by preventing backdrafting and
maintaining air circulation during an event of a fire where the fire fighters will have to enter the lift lobby during
rescue operations or fire fighting. In MITEC, there is a pressurisation ductwork inside the protected
pressurisation shaft that is situated in the lift lobbies on every floor. In the lift lobbies, fire dampers cannot be
used. Therefore, the pressurisation ductwork is used to maintain a positive pressure in the lift lobbies in order to
prevent smoke from entering and supply ventilated air into the lift lobbies.

4.3.2 Extract Ventilation System (Natural Inlet and Mechanical Extract)
4.3.2.1 Overview
A extract ventilation system is the reverse of an
supply ventilation system. It depressurizes the
building by using a mechanical fan to vacuum
out the interior air in order to create a negative
pressure at the interior which draws in the outer
air and displace the stale air. However, exhaust
ventilation system might draw contaminants
into the building along with the fresh air.
Therefore, filters are normally installed to
ensure clean inlet air by filtering out the
pollutants when air flows in. This system is
commonly used in kitchen, internal toilet and
bathroom, basement, attic and crawl space.
4.3.2.2 Case Study of Exhaust Ventilation System in MITEC
The building incorporates extract systems in the mechanical utility rooms and basement carpark, working to
ventilate the indoor enclosed rooms and dispersing contaminants in the air. The machinery and utilities must be
in suitable temperature and humidity to function at optimal levels.
4.3.2.2.1 Basement Car Park Exhaust System
In MITEC building, there are two levels of basement car park which requires exhaust system to ensure sufficient
supply of fresh air to the below ground and maintain the standard pressure level. It is performed through
ductworks that are evenly distributed to act as transfer pathway when mechanical fans drive the stale air out.

Summary:
The basement carpark system of MITEC complies with UBBL 1984 listed requirements of section 249 and the
third schedule as referred to the by- Law above. The regards to the by-Law stated above, it elaborates how the
ducting would work during the case of an emergency.
4.3.2.2.2 Utility Room Extract System
The exhaust system functions to regulate the air, extract
contaminants and more importantly, exhaust the smoke and
toxic fumes if the utility rooms were to have a fire emergency.
The reduce of oxygen within the space when air is being
extracted out by the exhaust vent results in the retardation of
fire spread. Also, the regulation of air flow within the space
remove heat produced by the machines within the utilities
room.
In MITEC, single duct system is used in the electric supply
room. The system filters the stale air and heat produced by the
machinery and automatically runs when thermometer senses a
rise in temperature. Axial fan is used for circulating air,
creating a low pressure in the duct and high pressure in the
room. Tubeaxial fan are suitable to be used in such system as
they have higher efficiency in removing large volume of air
through long sections of ductworks in relatively low pressure
and thus causing more air to be extracted into the ductwork
from the room.
The ventilation control panel is designed for reception and
distribution of power for the ventilation systems of the
building. It provides power for the ventilation equipments
such as electrical motors and fans, operating conditions,
modes and alarm of the ventilating system, management of the
ventilation system, and data transfer to the external scheduling
system. Besides that, the ventilation control panel has useful
functions, such as providing fresh air for the rooms, maintain
desired temperatures in rooms, protection of terminal
equipment, and emergency shutdown of the ventilation
systems.

The lift motor room utilises propeller fans to extract stale air in the room. The room is sufficiently ventilated
with the use of the 4 bladed propeller fan (belt drive fan) and natural inlets to allow outdoor air to be diffused
into the room. The fan is mounted on the wall with safety guards. Propeller fan is used as it is applicable within a
space with no attached ductwork needed to circulate high volume of air. The propeller fan also functions as
exhaust fan to draw out humid air from the lift motor room. The adjustable shuttles allow air to be deflected
while being drawn out.

air in concern for property damage as well as occupant safety. The ventilation concludes the requirement of the
section of 249, section 250 and section 251 as regards to the diagrams and figures above stating as the basement
carpark is fitted with necessity of an exhaust system to extract and disperse smoke, and harmful air particles
during a fire emergency.
(Uniform Building By-Law, 2006, pp. 87) (Original work published in 1984)
4.4 Conclusion
Mechanical ventilation system used in MITEC serves not only as a continuous channel for fresh air but also as a
safety feature like their staircase and lift lobby pressurization system. The lift lobby and enclosed staircases are
properly pressurised as following the requirement of UBBL 1984 under section 249, section 250 and section
251. MITEC complies with UBBL 1984 as it provides each component of mechanical ventilation accordingly to
the by-Law’s requirements. The indoor air quality of the building cannot be maintained with only HVAC system.
Hence it is important to implement mechanical ventilation system in the building for the occupant’s comfort and
safety.

5.1 Literature Review
Mechanical transportation is an integral part in modern building design where it provides usage towards the
vertical or horizontal movement of goods and people between different levels or floors in building. There are
two forms of mechanical transportation in a building, firstly vertical mechanical transportation which is provided
by lifts/elevators and escalators; secondly horizontal mechanical transportation provided by travelators. These
ensure the efficient and safe movement of people and goods in our everyday life, which in turn ensures an
improved standard of life and higher work efficiency.
5.2 Escalator
An escalator is a form of vertical mechanical transportation, and can be described as inclined, continuous
moving stairs with handrails that are designed to transport people from one floor of a building to another with
high efficiency. It has the capability to move large numbers of people with almost no waiting interval, and used
in places where lifts would be impractical. However, the escalator can be placed together with a lift at places
where there are lighter passenger flow, so the lift does not have to travel to the lower floor when there is heavier
traffic on the upper flows.
To determine the carrying capacity of an escalator, we need to look at its speed along the line of inclination and
width of tread. Modern escalators are usually inclined at an angle of 30°, electrically powered with a speed that
varies between 0.45 m/s to 0.7 m/s and may traverse vertical distances up to 18 metres. Tread widths range from
600mm to 1200mm, depending on the building’s need. A smaller width of 600 to 810mm width is suitable for
smaller scale buildings whereas a 1.0 to 1.2 m tread width is more suitable to accommodate to larger scale
buildings with heavier passenger flow.
Escalators can be typically configured into a few different types of arrangements, namely single, continuous,
parallel and crisscross, upon the consideration of installation costs and requirements for standard of service.

5.2.1 Case Study of Escalator in MITEC
5.2.1.1 Overview
There are mainly two models of escalators installed in MITEC, supplied and manufactured by KONE Elevator
Co. Ltd, namely the TravelMasterTM
110 and TransitMasterTM
140.
5.2.1.1.1 KONE TransitMasterTM
140 Escalator
Specifications:
● Operational environment: Indoor
● Speed: 0.65 m/s (with selectable reduction)
● Inclination: 30o
(for enhanced passenger comfort
and heavy duty environments)
● Step width: 1000mm (two passengers standing
side by side)
● Vertical rise: 12m to 15m (can go up to 18m)
● Step chain: Outside roller chains ((Ø 100 x 25
mm)
● Duty cycle: 20 to 24 hours/day
● Year of manufacture: January 2016
Standing at a unpreceded height of 15m within the
country, the TransitMasterTM
140 is the main escalator
within MITEC. The first length of the set spans a
vertical height of 15m between the ground and first
floor, whereas a second set spans 12m between the first
to second floor. It is a highly durable escalator that is
well suited for its location in front of the exhibition
halls and able to respond to the demand of high traffic
flow and round-the-clock operations especially when
there are major exhibitions, conferences or other
events.
The escalators in front of the exhibition halls are the
only set of escalators that employ the use of this
particular model, whereas the other three sets are of a
more modest model type.

The TravelMasterTM
110 is the most widely used type
of escalator within MITEC as it is more well suited to
cater to a relatively lighter daily passenger flow of
office workers as it is situated nearer to offices,
compared to the TransitMasterTM
140 type escalators
placed nearer to exhibition halls which need to sustain
a heavier passenger flow. It also allows connection
between floor levels of a relatively more moderate
height including to mezzanine floors, which ranges
from 7.5m to 12m in height.This model includes a
worm gear drive combined with the smart stardelta
operational mode which automatically regulates the
current needed depending on the actual step load.
There are three sets of escalators altogether in MITEC
that are of this type.

This arrangement is able to fulfill two-way
continuous passenger flow. It is also able to
respond to increase in one-way passenger flow
during peak hours by adjusting the travel
direction of escalators.
This arrangement is suitable for large-size
buildings or public construction where the
conveying times between these floors is
minimised to the furthest extent.

5.2.1.2.2 Combination of Parallel and Criss-cross Arrangement
This arrangement can be seen applicable to the
TransitMasterTM
140 type escalators in front of the
exhibition halls, which are also the main escalators
used to bring visitors to respective exhibition halls.
Set A escalators are in criss-cross arrangement with
Set B escalators. This pair spans a vertical height of
15m and only connects the ground and first floor of
the building. On the other hand, Set A and C have a
continuous two-way traffic parallel arrangement,
and this pair connects all three floors of the
building. Similarly, it is the same for Set B and C,
but its traffic flow is interrupted as passengers have
to walk around to reach the other escalator’s
platform.
5.2.1.2.3 Variations of Parallel Arrangement
All three sets of escalators provide two-way
passenger flow to each of the three main floors of
the building, particularly towards the office and
meeting rooms. However the line of circulation is
different for each floor.
Set A and B have a continuous arrangement where
the walking interval between each set is minimal. It
is suggested that it is because there are more
meeting rooms situated on the lower floors, hence
having a continuous arrangement can aid in
facilitating a more convenient circulation path,
especially for guests attending the meetings. Set B
and C however, has an interrupted passenger flow.

This is the typical parallel arrangement, and can be found used for the other two sets of escalators, one at the
basement and the other at the ground floor in front of the North entrance, both providing a two-way passenger
flow. The only difference between these two is that the latter set has three sets of escalators, two of the same
direction and one in the opposite, whereas the one at the basement only has one each for up and down
movement.

or a No-Entry sign at the landing areas.
5.2.1.3.2 Floor Plate and Comb
Floor plates also known as walk-on plates, are an entrance and exit for the passengers to stand on before moving
onto the steps of the escalator. At the same time, it provides mounting for the comb segments.
The comb is a replaceable section, with teeth that mesh (comb) into the step threads at both boarding and landing
areas. This is to prevent foreign objects from getting entangled into between the step threads in motion and floor
plate.

5.2.1.3.3 Moving Handrail
The handrail is a rubber conveyor belt that is looped
around a series of wheels, pulled along its track by a
chain that is connected to the main drive gear by a
series of pulleys. This belt is precisely configured so
that it moves at exactly the same speed as the steps, to
give riders some stability, acting as a convenient
handhold for passengers when they are using the
escalator.
5.2.1.3.4 Glass Panel Balustrade
The balustrade consists of the handrail and external
supporting structure of the escalator, which extends
above the steps to support the handrail. In the case of
MITEC, it is designed as an interior low deck which
has interior glass side panels to support the handrail
base. The 1100mm high balustrades also feature
fall-protection barriers and extended balustrade newel
ends to provide additional passenger protection.
5.2.1.3.5 Escalator Drive Machine
The drive machine together with the gear reducer provides torque to propel the step band at a controlled speed.
The motor is directly connected to the main shaft by the gear. Escalators in MITEC have the drive being located
outside the step band, which means easier, faster access for service technicians and minimal downtime. It is also
able to provide extra power for demanding people flow, with the possibility to combine two drives to power the
escalator step chain in heavy traffic environments.

5.2.1.4 Safety Features of Escalator
5.2.1.4.1 Demarcation Lines
Demarcation lines are strips of yellow usually, surrounding the perimeter of the step thread but mostly at the
front and rear edges of the threads. They are used to visually inform of step separation and create contrast
between the steps and comb segments.
5.2.1.4.2 Skirt Guard
The skirt guard is a row of brushes placed parallel to
the length of the escalator to ensure a safer ride for
passengers. When bristles of these brushes touch the
passenger they instinctively move to safer distances.
These brushes help the passengers know that they
are on the very edges of escalators which may result
in pinching and entrapment. It also tend to keep
clothing, luggage or loose cloth away from the skirts.
They also reduce static electricity from building to
the arcing point as the rubbing motion within
escalator causes static electricity to build.

5.3 Lift
An lift, or also known as elevator, is another form of vertical mechanical transportation. It is described as a
compartment or platform that moves in a vertical shaft to carry passengers or goods between levels of a
multistorey building. Most modern elevators are propelled by electric motors, either through a system of cables
and sheaves (pulleys) with the aid of a counterweight for drive transaction such as a hoist, or to pump hydraulic
fluid to raise a cylindrical piston known as a jack.
In a building with more than four storeys, an elevator is to be provided. It is also required within buildings with
less than four storeys to provide access for the elderly and disabled. To obtain an efficient service, the designer
when deciding on the number and type of lifts must also take into consideration several factors including the
type of building and nature of occupancy.
The quality of elevator performance is determined by the following few factors:
● The hoisting capacity
● Waiting interval
● Acceleration of car cab
● Speed of elevator
● Time taken for passengers to board and alight the elevator
● Working mechanism of the elevator
The diagram below shows the few types of lifts according to their different working mechanisms.

5.3.1 Case Study of Lifts in MITEC
5.3.1.1 Overview
There are ten locations in MITEC where lifts can be found, summing up to 17 lifts altogether, of which 15 are
passenger lifts and two are freight lifts. Even though the building only has three main superstructure levels,
another three mezzanine floors for each level and two basement levels, the amount of lifts are necessary to
respond to the nature of the building as an international exhibition centre that needs to accommodate huge
numbers of visitors almost daily, and also to ensure sufficient circulation points are provided within the large
building.
5.3.1.1.1 Passenger Lift
There are two different models of passengers lift in MITEC. The first type is the commonly seen lift that is
embedded into the walls of the building, whereas the second type is a see-through glass lift that is also
considered the centrepiece of the building.

5.3.1.1.2 Freight Lift
There are two heavy-duty freight lifts altogether found in MITEC, both placed at the rear end of the building
behind Hall 1 and Hall 4 respectively. The freight lift behind Hall 1 is smaller in size as it is located nearer to the
kitchen area and mainly used by kitchen workers to transport food and kitchen items. On the other hand, the
freight lift behind Hall 4 is bigger as it is mainly used to transport items to exhibition halls, which would require
a freight lift with larger loading capacity.

5.3.1.1.3 Location of Lifts
5.3.1.2 Traction Lift
Traction lift is the most common type of lift found in buildings, and its hoist mechanism is based on being lifted
by ropes. It moves in a direction, which raises and lowers the car in a shaft with wire ropes running over a series
of sheaves at the motor and the car itself. The ropes then terminated in a sliding counterweight that travels up
and down the same shaft at the same time as the car, which helps reduces the consumption of energy by the lift
as the counterweight is able to offset the weight of the car and its passengers so the lift motor does not need to
exert as much power to move the weight.
The traction lift is more suited for mid to high-rise buildings as it has a much higher travel speed than hydraulic
lifts. There are mainly three types of traction lifts: geared traction lift, gearless traction lift and machine
room-less lift. In MITEC, we can find two of the three types of traction lifts used in the building, namely the
gearless traction lift and machine room-less lift.

5.3.1.2.1 Gearless Traction Lift
The gearless traction lift is recognised by its
wheel that is attached directly to the lift
motor instead of being attached to the
gearbox as in the case of geared traction lifts.
This type of lift requires a machine room,
and is typically placed directly above the lift
shaft to minimise the length of rope and
optimize its efficiency. This type of hoist
mechanism is used for the standard
passenger lifts in MITEC.

Lift Motor Room
The lift motor room, also known as machine room or elevator machinery room. It is a room that houses the
machinery and electrical controls that operate a lift. The lift motor rooms in MITEC are situated directly above
their respective lift shafts at the rooftop of the building, and are fully enclosed, only accessible by authorised
personnels.
The lift motor room is to be kept well-ventilated for cooling of the components to prevent them from
overheating and subsequently suffering damage which may endanger the safety of passengers using the lifts. It is
also to be taken into consideration the transmission of sound, hence the concrete base of the machine should be
lined with insulation. The walls and ceilings are also painted to prevent accumulation of dust which may damage
the components and cause circuit failure due to poor electrical contacts.

5.3.1.2.2 Machine Room-less (MRL) Lift
The machine room-less lift is the result of technological advancement about 100 years ago that allows a
significant reduction in the size of the electric motors used with traction equipment. This system employs a
smaller sheave than conventional geared or gearless traction lifts. These newly designed permanent magnet
motors (PMM), together with the reduced sheave size allow the manufacturers to locate the machines in the
hoistway overhead, thus eliminating the need for a machine room over the hoistway. As s result, it is able to
optimise more usable space, reduce maintenance costs and reduce energy consumption levels. This type of
mechanism is used for the glass lift and freight lifts, replacing the need for hydraulic lifts.

Control Panel
The control panel is the most essential part of MRL lifts, as it acts to control all systems associated with the lifts.
Each lift has its personal protective device placed in their respective lift control panels rather than in the shaft, as
it is a switchboard and should be easily accessible. In terms of electrical engineering, to power and run each lift,
it must have an individual supply to the main switchboard and a main switch installed for each lift. A circuit
breaker is also installed in each lift to break the electrical supply in cases when a wrong signal is issued.

5.3.1.3 Control System
The control system is the main interface responsible for the coordination of all functioning aspects of a lift, for
example lift travel, opening of door, acceleration, signals and emergency notices, through the input and output
information. The control panel acts as a switch of the control system which is the brain of the entire system.

5.3.1.4.1 Lift Controller
The lift controller is a system which controls the lifts
either automatically or manually. The controller steps
down the incoming voltage to approximately 12V to
24V before directing it to the control system. The
lower voltage power supply is for the controlling
components and fixtures controlling the lift, whereas
only the lift motor requires a 3-phase power supply.
5.3.1.4.2 Overspeed Governor
Every lift system is equipped with an overspeed governor which acts as a device to stop or halt the lift when it
runs beyond the designated speed. This device is mostly found installed in a traction lift.

5.3.1.4.3 Electric Motor
The lift motor machine used in MITEC is the KONE EcoDisc permanent magnet synchronous machine, which is
used for both the gearless traction lifts and MRL lifts. Its assemblage comprises of a permanent magnet
synchronous motor, together with a vector-controlled drive system and energy regeneration options, providing
the highest total efficiency and minimizing both mechanical and electrical losses when compared to traditional
products.
5.3.1.4.4 Sheave
The drive sheave or also known as the traction sheave,
is described comprising of a metal sheave body or
pulley fixed to an electric motor and having a novel
cable groove liner around the circumference. The
sheave grips the hoist ropes, so when the sheave is
rotated, the ropes move too thus hoisting the lift car or
counterweight.

5.3.1.4.5 Counterweight
The counterweight acts as an opposite to the load by exerting an almost equal opposite force. Its main purpose is
to provide balance and stability when the lift is in motion, also optimizing the efficiency of lifting loads which
helps to save energy. The counterweight can be found located in the hoistway which hangs on the others side of
the sheave.
5.3.1.4.6 Guide Rail
Both the counterweight and lift car travel along the
guide rails along the sides of the lift shaft. Its purpose
is to prevent the counterweight and lift car from
swaying back and forth when in motion, and also work
as a breaking rail with safety measures to stop the car
during an emergency.

5.3.1.4.7 Lift Buffer
The lift buffer can be usually found at the bottom of the lift shaft. Its purpose is to stop or halt the descending
travel of the lift car or counterweight when it goes beyond its normal limit. This component is essential so as to
reduce the injury suffered by users during an emergency fall.
5.3.1.4.8 Suspension Rope
Suspension (hoist) rope (cable) is a device used to lift
or lower a load, represented by steel wire ropes which
act as suspension means for the car and counterweight.
These are usually used on traction type lifts, attached
to the crosshead and extending up into the lift motor
room looping over the sheave on the motor then down
to the counterweights.

The travelling cable is a vital link between the lift
car and controller. In conventional elevators, all
power transmission to the lift car and signal
information is transmitted through the traveling
cable.
5.3.1.5.4 Compensation Rope
A compensating rope is a welded-link or
plastic-coated chain, used to counterbalance the
weight of the hoist ropes when it reaches a certain
length that may tilt the balance of the car instead.
This allows an equal load distribution on the drive
sheave and motor, regardless of the car's position in
the hoistway. One end of the chain is fastened to the
bottom of the sling and the other end is attached to
the bottom of the counterweight frame.

5.3.1.5.4 Landing Door
The landing door, or also known as hoistway doors,
refers to the door that is visible from each floor of the
building. These doors are usually automatically
opened or closed by electric motors, but during
emergency cases it can be manually opened as well.
Safety devices are placed at each landing to prevent
inadvertent landing door openings and prevent the lift
car from moving unless it is in a locked position.
The difference between the car door and landing door
is that the car door is a part of the lift car itself, hence
travels throughout within the hoistway; whereas the
landing door are fixed to each landing floor nd is a
part of the building itself.
The type of landing door used in MITEC is the
automatic door type, which has a central opening door
comprising of two power-operated panels that part
simultaneously with a fluid motion.
5.3.1.6 Interior of Lift Car
5.3.1.6.1 Car Wall
Folded steel panels are used to enclose the lift car, along with the car floor and car ceiling that will be shown

5.3.1.6.2 Car Floor
The floor size ought to have the same dimensions as the lift car in terms of width and depth. The car floor must
have sufficient mechanical strength capacity to withstand forces that are applied during normal operations, safety
gear operation and impact of car to its spring buffers. There are two types of floor finish covers for lifts in
MITEC. The passenger lifts have a marble stone finish whereas the freight lifts and fire lifts have a rubber finish.
5.3.1.6.3 Car Ceiling
The car ceiling is designed to be able to withstand the weight of two people during maintenance operation
without permanent deformation. It is also to mount the emergency trap door, blower fan and balustrade. Lighting
fixtures are also mounted onto the car ceiling to provide lighting and improve the spatial experience when using
the lift.

The car operating panel (COP) is a panel mounted in the lift car comprising of the car operating controls, such as
call register buttons, door open and close button, alarm emergency stop button and other buttons or key switches
necessary for lift operation.
5.3.1.7 Floor Indicator and Designator
5.3.1.7.1 Floor Indicator
The floor indicator appears on the lintel of all lift car doors, and displays the floor destination of the lift. It
notifies passengers of the location of the lift, and upon the arrival of lift at each floor, a sound is emitted to notify
its arrival. The call button is used to request for a lift, consisting of an up and down button which illuminates to
indicate the request is received and a lift is on the way.

5.3.1.7.2 Floor Designator
The floor designator is placed on the wall adjacent to
the lifts in the lift lobby, indicating the floor level that
the passenger is currently on. In MITEC, a fire escape
plan is placed underneath the floor designator.
5.3.1.8 Safety Features of Lift
The lift transportation system is designed with many layers of safety features to ensure the utmost safety of its
passengers, hence is also considered one of the safest mode of transportation in the market. Each lift system
component are designed with integration of safety features, and this is applicable to the lifts found in MITEC as
well.
When an emergency arises, the alarm bells go off and the fire control room will swiftly verify the occurrence of
a fire. Once confirmed, the standard lifts will immediately be overridden and move to park at the ground floor to
allow passengers within to evacuate to the assembly point while the main power supply is disabled. At the same
time, the fireman’s lift is manually activated using the fireman’s lift switch by the firemen or authorised
personnel for evacuation or fire fighting purposes. As the main power supply had been earlier disabled, the fire
lift is powered by a backup generator.

(1) All lift lobbies shall be provided with smoke detectors.
[ Section 154 ] Emergency mode of operation in event of main power failure
(1) On failure of main power lifts shall return in sequence directly to the designated floor,
commencing with the fire lifts, without answering any car or landing calls and park with
doors open.
[ Section 155 ] Fire mode of operation
(2) If main power is available all lifts shall return in sequence directly to the designated floor,
commencing with the fire lifts, without answering any car or landing calls, overriding the
emergency stop button inside the car, but not any other emergency or safety devices, and
park with doors open.
(3) The fire lifts shall be available for use by the fire brigade on operation of the fireman’s
switch.
(4) Under this mode of operation, the fire lifts shall only operate in response to car calls but not
to landing calls in a mode of operation in accordance with by-law 154.
Part VIII: Fire Alarms, Fire Detection, Fire Extinguishment and Fire Fighting Access
[ Section 229 ] Means of access and fire fighting in buildings over 18.3 metres high
(5) A fire lift shall be provided to give access to each fire fighting access lobby or in the
absence of a lobby to the fire fighting staircase at each floor level.
(Uniform Building By-Law, 2006, pp. 58, 83) (Original work published in 1984)
Mechanical Transportation System Safety Features of Lift
5.3.1.8.1 Apron
A car apron or also known as toe guard is a vertical
protective board installed at the bottom of lift cars.
This guard protects the passengers from being exposed
to the open hoistway beneath the car if the doors are
opened when it is not at the landing.
5.3.1.8.2 Safety Door Edge
The car safety door edge functions to reverse the
direction of door operation if a person or object is hit
by the closing doors. There are also various other
door-safety systems, for example a multi-beam door
sensor that uses photoelectric beams or safety ray to
detect people or objects.
5.4 Conclusion
In MITEC, we can see the use of both escalators and lifts to provide vertical circulation, with sufficient numbers
of these around the whole building to accommodate the large amount of passenger flow during peak hours or
time. In terms of the mechanical transportation models, MITEC uses the latest technology by KONE which
ensures the maximum quality of performance of the transportation system for its users. The mechanical
transportation services provided are also in compliance with the requirements as stated in UBBL 1984, under
section 124 for providence of lifts and under section 153, 154, 155 and 229 for fire safety features. Due to the
mechanical transportation system in MITEC being subjected to constant heavy usage, proper maintenance of
these services must be carried out frequently to ensure that they are in good condition to be used safely to
transport passengers and goods.

CONCLUSION
Conclusion
We have chosen the Malaysia International Trade and Exhibition Centre as our case study building for its various
type of building services system such as active and passive fire protection system, air-conditioning system,
mechanical ventilation system and mechanical transportation system. Being a newly-established building with its
iconic enveloping form, leaving no stones unturned, we are being enthusiastic to learn about the practicality and
the implementation of technology of the services system.
Throughout the building service project 1, we have learnt how to identify and clarify the relevant information
that are related to active and passive fire protection system, air-conditioning system, mechanical ventilation
system and mechanical transportation system. This project had truly been a stepping stone for us to understand
the systems. We are now able to understand how each building services functions, for instances the connections
and position of different types of systems and how it complements each other. Through readings of various
guideline references and books, we could understand and are able to explain the principles and service systems
as well as space implications and regulations related to different services,
All in all, this project showed us the importance of practically and functional requirements of a building which
give comfort and safety to the occupants. It has been an eye opening experience for us to be exposed to the
building services system.

    Page 2 1.1 Abstract Thisproject aims to provide real-life case as an introduction to building services system installed in a multi-storey building. By introducing the common system used in the bigger volume of space with a variety of users, this knowledge can be integrated into future design studio project to ensure a practical and technically functional building design proposal. The case study building that our group have chosen is the Malaysia International Trade and Exhibition Centre. We are to analyse four system associated with building services which are active and passive fire protection system, air-conditioning system, mechanical ventilation system and mechanical transportation system. A thorough research was done prior to site visits. Two site visits were conducted to ensure complete data collection such as information and pictures of building services components. The complete data is then analysed with reference to Uniform Building By-Law 1984 (UBBL 1984), MS 1184 and MS 1525. We are to produce a documentation and analytical report with a 5-minute video to present our findings about the building services in MITEC. Pictures and video taken on site were used to visually portray the components of each building services system with a comprehensives study describing the function and its importance. All in all, we have learned a substantial amount of knowledge regarding to building services and its functions in creating a safe environment for the occupants of the buildings. The site visit provides us an insight and a realistic simulation of how building services are done in our local buildings and its implication towards a building design.

    2.0 Fire ProtectionSystem Fire protection system is the means to inhabit or mitigate the ignition, growth and spread of fire and its effects through the built environment. The system serves the purpose to extinguish the fire, control the fire and provide exposure protection to prevent domino effects. It can be classified into two types, which are active fire protection system and passive fire protection system. Active fire protection system is the component of fire detection and prevention which reacts to action or motion, while passive fire protection system is the component which seeks to contain or slow down the spread of a fire. In general, the role of active fire protection within the fire containment process is to detect, alert about, and seek to eliminate the fire hazard; passive fire protection, on the other hand, is in place in case the active component fails in its objective, and is put in place as more of a failsafe measure, rather than an active way to combat a fire hazard. 2.1 Active Fire Protection System 2.1.1 Literature Review Active Fire Protection System requires a certain amount of motion and response in order to for it to work during the event of fire. The system is either manually operated like a fire hydrant system or functioned automatically like the water sprinkler and cannon system.The design of fire fighting systems should conform to specified standards of Part VIII of Uniform Building By-Laws 2006 of Malaysia. Fire Detection System Detect the fire by detecting heat, smoke or flames Example : Smoke Detector Fire Alarm System Initiated by fire detection system and triggers the following active system Example : Fire Alarm Bell Automatic Active System Activated automatically to impede the spread of fire and prevent damage to other area of the buildings Example : Water Sprinkler System Manual Active System Managed mainly by firefighters or users who have knowledge of using them to combat and put out the fire Example : Fire Extinguisher F I R E Fire Protection System Building Services Active Fire Protection System Page 7 Malaysia International Trade And Exhibition Centre

    2.1.2 Water BasedSystem Water based system utilizes the inexpensive, non-toxic and readily available medium of water to discharge onto flames through a variety of carriers. The properties of water being able to be stored at atmospheric pressure and normal temperatures and to take the heat out of fire promptly make water better than any other recognized liquid for fighting the majority of fire. There are 5 types of water based systems that present in the case study building. Fire Protection System Building Services Active Fire Protection System Page 8 Malaysia International Trade And Exhibition Centre Fire Sprinkler System Extinguishes incipient fire without the intervention of human factor Water Cannon System Automated tracking system with positioning fire artillery, operating on the infrared sensor technology Dry Riser System Only charged with water by fire service pumping appliances when necessary W A T E R Sprinkler Water Tank Fire Hydrant System Source of water to assist fire authorities in a fire. 2.1.2.1 Water Pump System Water pump system is required to provide adequate pressure to meet the hydraulic demands of the case study building, especially when water supply is provided from the water storage tank located on ground floor. There are two main water tanks which are fire sprinkler - water cannon tank and hose reel - wet riser tank. Both of the tanks have their respective sets of water pump to facilitate the operation. The system operates when the pressure drops below a threshold. For instance, the fire sprinkler system pressure drops significantly when one or more fire sprinklers are activated or alternatively when other firefighting connections are opened, causing a pressure drop. In the building, the system mainly comprises of Jockey Pump, Duty Pump and Standby Pump. Wet Riser System Built-in water distribution system which is permanently charged with water Hose Reel System Manually operated and activated by opening a valve that enables the water flow into the system Water Pump System To provide a steady flow of water ranging different pressure levels Hose Reel and Wet Riser Tank

    2.1.2.1.1 Jockey Pump Jockeypump, also known as a pressure-maintenance pump, is a relatively small device that works together with the fire pump. It is designed to keep the pressure in the system elevated to a specific level when the system is not in use, so that the fire pump doesn’t have to run all the time. This prevents the sprinklers from going off unnecessarily. Moreover, since pipes are susceptible to leakage over time, the water pressure inside them tends to go down. As soon as the jockey pump senses this, it fills them back up to normal pressure. Also, it can also help prevent the system from damage when a fire happens and pressurized water rushes into the pipes by regulating the pressure. It is powered by electric supply and is connected directly to the fire sprinkler water tank.

    Fire Protection System BuildingServices Active Fire Protection System Page 12 Malaysia International Trade And Exhibition Centre 2.1.2.2 Fire Sprinkler System Fire sprinkler system acts as the crucial first-line of active fire protection. The system extinguishes or prevents spreading of fire in its early stage, keeping the fire under control until the fire brigade arrives. Water extinguishes the given area during fire, cools building structures and the surrounding area and at higher temperatures it evaporates quickly, displacing oxygen and thus creates an inert atmosphere, which prevents the access of oxidant, i.e. the atmospheric oxygen that is needed for combustion. It consists of distribution piping system that is permanently attached to building structures, valve station and sprinkler heads that are firmly attached to the distribution pipes in the protected area. Pipeline network together with sprinkler heads are connected to a water source that provides adequate pressure.

The system employs fixed fire sprinkler heads and sprinkler piping filled with pressurized water supplied from a dependable source at all times. Sprinkler heads are equipped with a glass trigger filled with a glycerin-based liquid that expands with temperature. As the liquid expands, it shatters its glass confines and activated the sprinkler head, water is then discharged immediately onto the fire. The sprinkler heads are not all activated at once since each one of them is independent, thereby minimizing water damage. Only sprinklers in the area of the fire that have reached the temperature required to melt. The type of bulb used in the case study building is red liquid bulb.

Beneath the sprinkler heads, a valve keeps the water from leaking out. When the sprinkler head is triggered, the valve is opened and pressurized water is released from the pipe system. It’s important for water in a fire sprinkler system to be pressurized. This allows the water to spray outward in an arc to more thoroughly douse the fire and prevent it from reigniting.The alarm check valve is a key component of the wet pipe system. It is designed to indicate when a sprinkler has operated as well as to provide a system check valve. The alarm check valve serves as a check valve by holding the pressurized water above the clapper and preventing reverse flow from the sprinkler piping. The valve initiates an alarm during a sustained flow of water by operating a water motor alarm and alarm pressure switch. When it is installed with the water motor alarm, the system can provide a local alarm even when electric power is lost. Diagram 2.8 Both pendant and upright sprinkler head spray water in circle pattern 2.1.2.1.3 Upright Fire Sprinkler An upright fire sprinklers spray water upward to a concave deflector, producing a dome-shaped spray pattern. They are used mostly in places where obstructions may block water spray during a fire, and their height allows them to aim water around possible obstacles. While they can't be hidden behind a cover plate, system design can make upright models less of an eyesore. Figure 2.12 Upright fire sprinkler

    2.1.3 Non-Water BasedSystem Non-water fire suppression system is a fire suppression mechanism which works on putting the fire out without using water-based agents. A common belief among the people is that the best way to fight fire is by using water. But that is not the case, as not all fires can be dozed out using water. There are many cases where a standard water-based fire protection system cannot and will not protect the building in the event of a fire. For instances where you are fighting electrical fires, certain chemicals, metals, or flammable materials less dense than water you need a specialty system to extinguish fires. In fact, most of the time water can cause more damage than damage-controlling. 2.1.3.1 Fire Suppression System Fire suppression system in MITEC is designed to protect a specific hazard and may be used to supplement the active fire protection system by providing protection in the fire risk areas. To ensure proper fire protection, the extinguishing agent compatibility with the protected hazard is concerned. The system functions to protect a specific hazard when water is not a key suppression agent. This article will review some of the basic concepts of three of these types of alternative fire suppression systems; wet chemical, dry chemical, and foam suppression systems. Fire Protection System Building Services Active Fire Protection System Page 24 Malaysia International Trade And Exhibition Centre Fire Suppression System The system consists of dry chemical such as phosphate compound monoammonium phosphate. The dry chemical extinguishes the fire by interrupting the chemical reaction and cutting out the oxygen source. Example : ABC Dry Powder Fire Extinguisher Dry Chemical System Gas System The system are stored as liquid, with nitrogen used to pressurise it. Upon releasing the chemical agent, chemical reacts with the fire and extinguishes it. It is suited to data rooms and switch rooms in MITEC. Example : Carbon Dioxide Fire Extinguisher Carbon Dioxide Suppression System

    2.1.3.1.1 ABC DryPowder Fire Extinguisher The ABC Dry Powder Fire Extinguisher can be seen in most of the place in MITEC. It is a portable fire extinguisher which can take down all the major kinds of fires though it specially tackles Class A, B and C fires. The dry chemical in the units is monoammonium phosphate. When the ammonium phosphate and aluminum sulfate particles are ejected with massive force from the extinguisher, they fuse together to form an airtight barrier that completely chokes off the oxygen from a fire. The powder chemical works differently to extinguish the various fires. It chemically insulates a Class A fire, smothers and breaks the chain reaction for a Class B fire and will not conduct electricity back to the operator in a Class C fire. However it is not recommended to be used in enclosed spaces. This is because the powder can be easily inhaled, and also the residue is very difficult to clean up after. Class C Flammable gases, such as butane, methane and propane Figure 2.34 ABC Fire Extinguisher in MITEC Class A Ordinary combustibles, such as wood, paper, cardboard and cloth as well as solid plastic Class B Flammable liquids like gasoline, kerosene and diesel fuel, oil-based paint and grease Figure 2.35 ABC Fire Extinguisher 2.1.3.1.2 Carbon Dioxide Fire Extinguisher Carbon dioxide fire extinguisher types smothers the fire by displacing oxygen in the air but do not leave any substances unlike the other fire extinguishers. It is particularly useful for offices and computer server rooms in MITEC where electrical fires may likely to occur. They also put out Class B fires (flammable liquids, such as paint and petroleum). It suffocates fires by displacing the oxygen the fire needs to burn. It is placed near to the source of the fire risk areas and the fire exits in MITEC.

    2.1.3.1.3 Carbon DioxideSuppression System Carbon dioxide (CO2) is a colorless, odorless, and chemically inert gas that is both readily available and electrically non-conductive that leaves no residue behind. This means any sensitive equipment that is in the protected space is not damaged by the CO2, which reduces downtime and costs. Once the CO2 has dispersed to safe levels from the protected space, personnel can access any damage from the fire or smoke and quickly get back to work with no cleanup needed. It extinguishes fire primarily by lowering the level of oxygen that supports combustion. This mechanism of fire suppression is highly effective, requiring minimal clean-up and is used in normally unoccupied hazard locations or otherwise avoided by personnel when discharged. In MITEC, each electrical room has an carbon dioxide suppression system. Fire Protection System Building Services Active Fire Protection System Page 26 Malaysia International Trade And Exhibition Centre Diagram 2.14 System Operation Overview UBBL 1984 Part VIII: Fire Alarms, Fire Detection, Fire Extinguishment and Fire Fighting Access [ Section 227 ] Portable Extinguishers Portable extinguisher shall be provided in accordance with the relevant codes of practice and shall be sited in prominent positions on exit routes to be visible from all directions and similar extinguishers in a building shall be of the same method of operation. Summary (Fire Extinguisher) : The fire extinguishers system in MITEC meets the UBBL 1984 requirements listed under Section 227, (3). The fire extinguishers are strategically placed at many locations to be easily accessible by users in the building during the event of fire. System Operation A carbon dioxide fire suppression system eliminates the oxygen to suppress the fire. The system is equipped with a smoke and heat detector which will trigger the alarm system and send signal to the fire control room through the fire control panel upon detecting smoke and temperature rise. It then releases the carbon dioxide agent into the space it is protecting. After 30 seconds, all the gas inside will be discharged through piping, leaving only carbon dioxide inside with the fire curtain opened and smoke damper closed. The drop in oxygen level quickly causes the fire to be suppressed or extinguished. On the control panel outside, if green light lights up, it means that personnel is free to enter the room whereas if the red light lights up, it means that the carbon dioxide agent is being discharged and the room cannot be entered.

    2.1.5 Fire DetectionSystem A Fire Detection System (FDS) is an alarm system that receives data on, assesses and then responds to event reported by various detector which usually consists of smoke detector, heat detector and damper which play a significant role in protecting the the safety of emergency personnel. Fire Detection System are permanently installed manual and automatic systems to detect fires at the earliest stage, warn those affected and quickly inform the relevant emergency service. A properly installed and maintained Fire Detection System commit to save lives and largely reduces building property damage. To be useful, fire detection system should work with fire alarm system to become a life-safety system which ensure a rapid detection of fire.

All parts of MITEC to be monitored are equipped with a network of electric cables and automatic or non-automatic detectors. These detectors are operated either manually or triggered automatically by heat, visible or invisible smoke, or flames. From here, system are all connected and communicate both with each other with a central control monitoring location. Only the detectors in the immediate vicinity of the fire are activated, sending a report to the fire detection control panel. The interconnectivity allows the control personnel to identify the location of “address” where the initial detection occurred. Information detected will be directed to emergency response team immediately for the fire rescue operation. Once the fire has been extinguished, the system can be made operational again quickly and simply. Diagram 2.15 Overall layout of Fire Detection System

    2.1.5.2 Smoke Detector Smokedetector serve as an indicator for the occurrence of fire which plays a crucial role in Fire Detection System. As the first component which can react to the fire, detector will transfer signal to fire control panel in fire control room to activates the alarm system. In MITEC, there are generally two types of smoke detectors which is ionization smoke detector and photoelectric smoke detector. Fire Protection System Building Services Active Fire Protection System Page 31 Malaysia International Trade And Exhibition Centre Figure 2.50 Smoke Detector in Mega Exhibition Hall Figure 2.51 Smoke Detector in Control Room The smoke detector provided in Mega Exhibition Hall are mostly ionization smoke detector which generally more sensitive and responsive to flaming fires. This type of smoke detector sensitive at sending small particles, which tend to be produced in greater amount by hot, flaming fires, that are consuming combustible materials rapidly and may spread quickly. In the ionization smoke detector, if the smoke particle enters the chamber of the ionization detector it will reduce air ionization inside the chamber of the ionization detector and triggers the alarm to alert the building occupants. The photoelectric smoke detector which uses a light beam to help detect the presence of smoke. This alarm types are more effective at sounding when a fire originates from a smoldering source. Smoldering fires may fill a room with dangerous gases before a fire ever erupts. In a result, it is more suitable to be implied in small room which smoke could be accumulate in a short time of period. The presence of suspended smoke particles in the chamber scatters the light beam. This scattered light is detected by the light sensitive sensor which sets off the alarm before the smouldering fires bursting into flame.

Heat detector usually has a lower false alarm rate but it is slower than smoke detector in detecting fires. In general, there are two types of heat detectors which are fixed temperature heat detector and rate-of-rise heat detector. Fixed Temperature Heat Detector: Operate when the ambient temperature increases sufficiently to predetermined level where the heat detector will operate. The heat is accumulated at the sensitive element due to a thermal lag. This causes the temperature of the device to reach its operating temperature a while after the surrounding air temperature exceeds the device temperature. When this happens, the detector is activated and an alarm is sounded. Rate-of-rise Heat Detector (ROR): ROR heat detectors may not respond to slowly developing fires. In order to detect slowly developing fires, usually a fixed temperature element is added to the ROR detector which will be activated when the element reaches the pre-set threshold temperature then triggered the alarm system. Figure 2.55 Heat Detector on ceiling of ground floor Addressable heat detector provided in MITEC are installed in concourse are on ground floor and Mega Exhibition Hall. Heat detectors have a common profile with photoelectric and ionization smoke detectors but have a lower air flow resistance case made of self-extinguishing white polycarbonate.

    Fire Rated Lock 2.2.3.3 FireContainment Fire containment systems are designed to isolate affected areas of fire origin by preventing smoke and heat and ensuring small fires are not allowed to escalate into the full-scale blazes. Even if the fire is relatively small and contained, the spread of smoke can cause some serious problems in the long-term, even to remote and otherwise unaffected parts of a building. When smoke cools, it drops, which can cause a building to become smoke logged. But when the fire and the smoke is contained, it’s not allowed to cool, so it remains relatively buoyant. This can boost the efficiency of smoke extractors and other ventilation systems. 2.2.3.3.1 Fire Rated Door A fire door is one of the device of Passive Fire Protection system. It is fire-resistant and to reduce the spread of fire and smoke between a separate compartments of a structure and to enable safe egress from a building.

These doors also complies with the requirement of having automatic closing function. For security purposes, the doors are only accessible for employees of MITEC. Therefore, it is difficult for public to access these areas. However during an emergency, a break glass is available right next to the door for access. In conclusion, MITEC fire rated doors have complied with the requirements of UBBL stated above 2.2.3.3.2 Fire Rated Floor Fire rated floor is a slab of a building that is fire resistance. Reinforced concrete structures with complex inner geometry under the effect of high temperature considering void former materials. The materials has the highest fire resistance classification and non-combustible. Slow rate of heat transfer while having structural integrity Concrete’s inherent material properties, it can be used to minimise fire risk for the lowest initial cost while requiring the least in terms of ongoing maintenance. Other materials rely on fire protection, fire safety engineering or rate of loss of combustion. This reliance on fire protection, fire safety engineering and rate of combustion makes them unforgiving of workmanship errors, future changes as simple as changing light fittings, compliance with management procedures and human behaviour.

    2.2.3.3.3 Fire RatedWall A fire-rated wall is a feature of a building’s passive fire protection system that has been checked and certified by the proper regulatory agency. There are two basic types of fire-rated walls: true firewalls and fire barrier walls. The first is a structurally stable wall that also is certified to prevent fire from spreading from one side of a building to the other. Fire barrier walls, on the other hand, provide fire-rated protection while not being structurally sound. A fire barrier wall are interior walls that extend from the floor‐to‐floor or floor‐to‐roof, including concealed and interstitial spaces. They are designed to sub‐divide portions of the building, and can be supported by structures, such as roofs, columns or floors. All support structures should have a fire-resistant rating no less than that of the fire barrier they support. Fire barriers restrict the initial flow of heat within the area of origin, which provides building occupants with adequate time to evacuate to safe areas. These walls will typically have a 2 to 3‐hour fire‐resistance rating. In MITEC, a fire barrier wall are used with a material of reinforced concrete to provide fire resistance to the space in the building.

    4.1 Literature Review Ventilationplays a vital role in building to remove the stale air and replace it with fresh air from an external environment.Ventilation system can be classified into two categories, natural ventilation and mechanical ventilation. Both system had implemented in the building design as the need suited to the nature of building. In mechanical ventilation system, components such as fan, filter, ductwork, dampers, grille and diffusers are used to expel the stale air, working as a makeup air supply to enhance indoor quality. Mechanical ventilation can be spotted usually in enclosed spaces that require good airflow. Importance of mechanical ventilation system: ● Preservation of oxygen content and removal of carbon dioxide ● Control of humidity levels ● Prevention of heat concentrations from machinery, lighting and people ● Solution for unreliable natural ventilation system ● Reduce accumulation of moisture, dust, bacteria and smoke ● Dilution and disposal of contaminants. There are various types of ventilation methods each serving different purposes and mechanical ventilation are often used when natural ventilation is insufficient. There are 3 types of mechanical ventilation system: ● Supply system ● Extract system ● Balanced / Combined system 4.2 Components of Mechanical Ventilation System 4.2.1 Mechanical Fans Fan is an important component of a mechanical ventilation system which is used to create air movement. It provides a function of removing hot, heat and polluted air. The mechanical fan consists of a rotating arrangement of vanes or blades that aids in capturing contaminants by carrying them to the air cleaning devices through duct system. It brings in outdoor air for comfort ventilation or convection cooling of buildings at night as well as provide constant indoor circulation. There are mainly three types of fan, which are propeller fan, axial fan and centrifugal fan as shown in the figures below.

    Mechanical Ventilation System 4.3Types of Mechanical Ventilation System 4.3.1 Supply Ventilation system (Mechanical Inlet and Natural Extract) 4.3.1.1 Overview Supply ventilation system applies the concept of mechanical inlet and natural extract. It works by pressurizing the building. Fresh air is drawn in by a mechanical fan and is distributed to many rooms forcing the stale air out through natural extract exit such as windows or door gaps by using a fan and duct system. This continuous supply system allows occupant to have better control of the air that move into the building through filter option. The constant pressurization of inlet air creates a positive pressure which prevent outside contaminants from entering thus it is suitable to be used in a polluted and noisy environment. 4.3.1.2 Case Study of Supply Ventilation System in MITEC The building incorporates supply systems in enclosed staircase pressurization system and lift lobby pressurization system. Both work together to provide a smoke-free escape route in case of fire in the building. It will also be a useful smok-free route for the firefighter to carry out firefighting operation. 4.3.1.2.1 Staircase Pressurisation System One of the most hazardous situations that can be faced in a building is smoke. While fires themselves are often damaging, it is the smoke that can cause the most injuries. In order to protect a building’s occupants, as well as furnishings and equipment, a smoke control system is needed to control the flow of smoke and keeps smoke from spreading throughout the building and gives the building’s occupants a clear evacuation route. Building Services Literature Review Page 108 Malaysia International Trade And Exhibition Centre Diagram 4.5 Operation of supply ventilation
  • 122.
    The primary meansof controlling smoke movement is by creating air pressure differences between smoke control zones. In pressurization, air is injected from the pressurization system located at the rooftop into the protected escape routes, which include the emergency escape staircase. Higher pressure is established inside the staircase than in adjacent part of the building. In this way, air moves into the smoke zone from the adjacent areas and smoke is prevented from dispersing throughout the building.

    Some of thestaircases in MITEC are not enclosed. Therefore, the pressurized system was not adopted due to the reason that natural ventilation was able to improvised as a tool to generate air circulation. The staircases highlighted in Diagram 4.8 complies with UBBL 1984, by-law 198, which it has louvre heat ventilators for each storey in the staircase shafts to supply permanent natural ventilation.

    Mechanical Ventilation System 4.3.2Extract Ventilation System (Natural Inlet and Mechanical Extract) 4.3.2.1 Overview A extract ventilation system is the reverse of an supply ventilation system. It depressurizes the building by using a mechanical fan to vacuum out the interior air in order to create a negative pressure at the interior which draws in the outer air and displace the stale air. However, exhaust ventilation system might draw contaminants into the building along with the fresh air. Therefore, filters are normally installed to ensure clean inlet air by filtering out the pollutants when air flows in. This system is commonly used in kitchen, internal toilet and bathroom, basement, attic and crawl space. 4.3.2.2 Case Study of Exhaust Ventilation System in MITEC The building incorporates extract systems in the mechanical utility rooms and basement carpark, working to ventilate the indoor enclosed rooms and dispersing contaminants in the air. The machinery and utilities must be in suitable temperature and humidity to function at optimal levels. 4.3.2.2.1 Basement Car Park Exhaust System In MITEC building, there are two levels of basement car park which requires exhaust system to ensure sufficient supply of fresh air to the below ground and maintain the standard pressure level. It is performed through ductworks that are evenly distributed to act as transfer pathway when mechanical fans drive the stale air out.

    Mechanical Ventilation System Inducedjet fans are positioned at a sufficient distance away from other mechanical service components such as sprinklers, signs and ductworks. The fans produce a high velocity jet of air, in turn moving a larger quantity of air surrounding the fan through a process known as entrainment. The amount of air entrained by a single fan increases with the velocity and the quantity of air being discharged by the fan.The extract of air is run by the fan rooms which are located at the ends of the parking area.

    Mechanical Ventilation System Summary: Thebasement carpark system of MITEC complies with UBBL 1984 listed requirements of section 249 and the third schedule as referred to the by- Law above. The regards to the by-Law stated above, it elaborates how the ducting would work during the case of an emergency. 4.3.2.2.2 Utility Room Extract System The exhaust system functions to regulate the air, extract contaminants and more importantly, exhaust the smoke and toxic fumes if the utility rooms were to have a fire emergency. The reduce of oxygen within the space when air is being extracted out by the exhaust vent results in the retardation of fire spread. Also, the regulation of air flow within the space remove heat produced by the machines within the utilities room. In MITEC, single duct system is used in the electric supply room. The system filters the stale air and heat produced by the machinery and automatically runs when thermometer senses a rise in temperature. Axial fan is used for circulating air, creating a low pressure in the duct and high pressure in the room. Tubeaxial fan are suitable to be used in such system as they have higher efficiency in removing large volume of air through long sections of ductworks in relatively low pressure and thus causing more air to be extracted into the ductwork from the room. The ventilation control panel is designed for reception and distribution of power for the ventilation systems of the building. It provides power for the ventilation equipments such as electrical motors and fans, operating conditions, modes and alarm of the ventilating system, management of the ventilation system, and data transfer to the external scheduling system. Besides that, the ventilation control panel has useful functions, such as providing fresh air for the rooms, maintain desired temperatures in rooms, protection of terminal equipment, and emergency shutdown of the ventilation systems.

    5.0 Mechanical TransportationSystem 5.1 Literature Review Mechanical transportation is an integral part in modern building design where it provides usage towards the vertical or horizontal movement of goods and people between different levels or floors in building. There are two forms of mechanical transportation in a building, firstly vertical mechanical transportation which is provided by lifts/elevators and escalators; secondly horizontal mechanical transportation provided by travelators. These ensure the efficient and safe movement of people and goods in our everyday life, which in turn ensures an improved standard of life and higher work efficiency. 5.2 Escalator An escalator is a form of vertical mechanical transportation, and can be described as inclined, continuous moving stairs with handrails that are designed to transport people from one floor of a building to another with high efficiency. It has the capability to move large numbers of people with almost no waiting interval, and used in places where lifts would be impractical. However, the escalator can be placed together with a lift at places where there are lighter passenger flow, so the lift does not have to travel to the lower floor when there is heavier traffic on the upper flows. To determine the carrying capacity of an escalator, we need to look at its speed along the line of inclination and width of tread. Modern escalators are usually inclined at an angle of 30°, electrically powered with a speed that varies between 0.45 m/s to 0.7 m/s and may traverse vertical distances up to 18 metres. Tread widths range from 600mm to 1200mm, depending on the building’s need. A smaller width of 600 to 810mm width is suitable for smaller scale buildings whereas a 1.0 to 1.2 m tread width is more suitable to accommodate to larger scale buildings with heavier passenger flow. Escalators can be typically configured into a few different types of arrangements, namely single, continuous, parallel and crisscross, upon the consideration of installation costs and requirements for standard of service.

    5.2.1 Case Studyof Escalator in MITEC 5.2.1.1 Overview There are mainly two models of escalators installed in MITEC, supplied and manufactured by KONE Elevator Co. Ltd, namely the TravelMasterTM 110 and TransitMasterTM 140. 5.2.1.1.1 KONE TransitMasterTM 140 Escalator Specifications: ● Operational environment: Indoor ● Speed: 0.65 m/s (with selectable reduction) ● Inclination: 30o (for enhanced passenger comfort and heavy duty environments) ● Step width: 1000mm (two passengers standing side by side) ● Vertical rise: 12m to 15m (can go up to 18m) ● Step chain: Outside roller chains ((Ø 100 x 25 mm) ● Duty cycle: 20 to 24 hours/day ● Year of manufacture: January 2016 Standing at a unpreceded height of 15m within the country, the TransitMasterTM 140 is the main escalator within MITEC. The first length of the set spans a vertical height of 15m between the ground and first floor, whereas a second set spans 12m between the first to second floor. It is a highly durable escalator that is well suited for its location in front of the exhibition halls and able to respond to the demand of high traffic flow and round-the-clock operations especially when there are major exhibitions, conferences or other events. The escalators in front of the exhibition halls are the only set of escalators that employ the use of this particular model, whereas the other three sets are of a more modest model type.

    5.2.1.1.2 KONE TravelMasterTM 110Escalator Specifications: ● Operational environment: Indoor ● Speed: 0.4 m/s (with inverter) ● Inclination: 30o (for enhanced passenger comfort and heavy duty environments) ● Step width: 1000mm (two passengers standing side by side) ● Vertical rise: 7.5m to 12m (can go up to 13m) ● Step chain: Inside roller chains ● Duty cycle: 12 to 14 hours/day ● Year of manufacture: January 2015 The TravelMasterTM 110 is the most widely used type of escalator within MITEC as it is more well suited to cater to a relatively lighter daily passenger flow of office workers as it is situated nearer to offices, compared to the TransitMasterTM 140 type escalators placed nearer to exhibition halls which need to sustain a heavier passenger flow. It also allows connection between floor levels of a relatively more moderate height including to mezzanine floors, which ranges from 7.5m to 12m in height.This model includes a worm gear drive combined with the smart stardelta operational mode which automatically regulates the current needed depending on the actual step load. There are three sets of escalators altogether in MITEC that are of this type.

    5.2.1.2.2 Combination ofParallel and Criss-cross Arrangement This arrangement can be seen applicable to the TransitMasterTM 140 type escalators in front of the exhibition halls, which are also the main escalators used to bring visitors to respective exhibition halls. Set A escalators are in criss-cross arrangement with Set B escalators. This pair spans a vertical height of 15m and only connects the ground and first floor of the building. On the other hand, Set A and C have a continuous two-way traffic parallel arrangement, and this pair connects all three floors of the building. Similarly, it is the same for Set B and C, but its traffic flow is interrupted as passengers have to walk around to reach the other escalator’s platform. 5.2.1.2.3 Variations of Parallel Arrangement All three sets of escalators provide two-way passenger flow to each of the three main floors of the building, particularly towards the office and meeting rooms. However the line of circulation is different for each floor. Set A and B have a continuous arrangement where the walking interval between each set is minimal. It is suggested that it is because there are more meeting rooms situated on the lower floors, hence having a continuous arrangement can aid in facilitating a more convenient circulation path, especially for guests attending the meetings. Set B and C however, has an interrupted passenger flow.

At the same time, it provides mounting for the comb segments. The comb is a replaceable section, with teeth that mesh (comb) into the step threads at both boarding and landing areas. This is to prevent foreign objects from getting entangled into between the step threads in motion and floor plate.

    5.2.1.3.3 Moving Handrail Thehandrail is a rubber conveyor belt that is looped around a series of wheels, pulled along its track by a chain that is connected to the main drive gear by a series of pulleys. This belt is precisely configured so that it moves at exactly the same speed as the steps, to give riders some stability, acting as a convenient handhold for passengers when they are using the escalator. 5.2.1.3.4 Glass Panel Balustrade The balustrade consists of the handrail and external supporting structure of the escalator, which extends above the steps to support the handrail. In the case of MITEC, it is designed as an interior low deck which has interior glass side panels to support the handrail base. The 1100mm high balustrades also feature fall-protection barriers and extended balustrade newel ends to provide additional passenger protection. 5.2.1.3.5 Escalator Drive Machine The drive machine together with the gear reducer provides torque to propel the step band at a controlled speed. The motor is directly connected to the main shaft by the gear. Escalators in MITEC have the drive being located outside the step band, which means easier, faster access for service technicians and minimal downtime. It is also able to provide extra power for demanding people flow, with the possibility to combine two drives to power the escalator step chain in heavy traffic environments.

They are used to visually inform of step separation and create contrast between the steps and comb segments. 5.2.1.4.2 Skirt Guard The skirt guard is a row of brushes placed parallel to the length of the escalator to ensure a safer ride for passengers. When bristles of these brushes touch the passenger they instinctively move to safer distances. These brushes help the passengers know that they are on the very edges of escalators which may result in pinching and entrapment. It also tend to keep clothing, luggage or loose cloth away from the skirts. They also reduce static electricity from building to the arcing point as the rubbing motion within escalator causes static electricity to build.

    5.3 Lift An lift,or also known as elevator, is another form of vertical mechanical transportation. It is described as a compartment or platform that moves in a vertical shaft to carry passengers or goods between levels of a multistorey building. Most modern elevators are propelled by electric motors, either through a system of cables and sheaves (pulleys) with the aid of a counterweight for drive transaction such as a hoist, or to pump hydraulic fluid to raise a cylindrical piston known as a jack. In a building with more than four storeys, an elevator is to be provided. It is also required within buildings with less than four storeys to provide access for the elderly and disabled. To obtain an efficient service, the designer when deciding on the number and type of lifts must also take into consideration several factors including the type of building and nature of occupancy. The quality of elevator performance is determined by the following few factors: ● The hoisting capacity ● Waiting interval ● Acceleration of car cab ● Speed of elevator ● Time taken for passengers to board and alight the elevator ● Working mechanism of the elevator The diagram below shows the few types of lifts according to their different working mechanisms.

    5.3.1.1.3 Location ofLifts 5.3.1.2 Traction Lift Traction lift is the most common type of lift found in buildings, and its hoist mechanism is based on being lifted by ropes. It moves in a direction, which raises and lowers the car in a shaft with wire ropes running over a series of sheaves at the motor and the car itself. The ropes then terminated in a sliding counterweight that travels up and down the same shaft at the same time as the car, which helps reduces the consumption of energy by the lift as the counterweight is able to offset the weight of the car and its passengers so the lift motor does not need to exert as much power to move the weight. The traction lift is more suited for mid to high-rise buildings as it has a much higher travel speed than hydraulic lifts. There are mainly three types of traction lifts: geared traction lift, gearless traction lift and machine room-less lift. In MITEC, we can find two of the three types of traction lifts used in the building, namely the gearless traction lift and machine room-less lift.

    5.3.1.2.1 Gearless TractionLift The gearless traction lift is recognised by its wheel that is attached directly to the lift motor instead of being attached to the gearbox as in the case of geared traction lifts. This type of lift requires a machine room, and is typically placed directly above the lift shaft to minimise the length of rope and optimize its efficiency. This type of hoist mechanism is used for the standard passenger lifts in MITEC.

    Lift Motor Room Thelift motor room, also known as machine room or elevator machinery room. It is a room that houses the machinery and electrical controls that operate a lift. The lift motor rooms in MITEC are situated directly above their respective lift shafts at the rooftop of the building, and are fully enclosed, only accessible by authorised personnels. The lift motor room is to be kept well-ventilated for cooling of the components to prevent them from overheating and subsequently suffering damage which may endanger the safety of passengers using the lifts. It is also to be taken into consideration the transmission of sound, hence the concrete base of the machine should be lined with insulation. The walls and ceilings are also painted to prevent accumulation of dust which may damage the components and cause circuit failure due to poor electrical contacts.

    5.3.1.2.2 Machine Room-less(MRL) Lift The machine room-less lift is the result of technological advancement about 100 years ago that allows a significant reduction in the size of the electric motors used with traction equipment. This system employs a smaller sheave than conventional geared or gearless traction lifts. These newly designed permanent magnet motors (PMM), together with the reduced sheave size allow the manufacturers to locate the machines in the hoistway overhead, thus eliminating the need for a machine room over the hoistway. As s result, it is able to optimise more usable space, reduce maintenance costs and reduce energy consumption levels. This type of mechanism is used for the glass lift and freight lifts, replacing the need for hydraulic lifts.

    Control Panel The controlpanel is the most essential part of MRL lifts, as it acts to control all systems associated with the lifts. Each lift has its personal protective device placed in their respective lift control panels rather than in the shaft, as it is a switchboard and should be easily accessible. In terms of electrical engineering, to power and run each lift, it must have an individual supply to the main switchboard and a main switch installed for each lift. A circuit breaker is also installed in each lift to break the electrical supply in cases when a wrong signal is issued.

    5.3.1.4 Main Componentsof Lift 5.3.1.4.1 Lift Controller The lift controller is a system which controls the lifts either automatically or manually. The controller steps down the incoming voltage to approximately 12V to 24V before directing it to the control system. The lower voltage power supply is for the controlling components and fixtures controlling the lift, whereas only the lift motor requires a 3-phase power supply. 5.3.1.4.2 Overspeed Governor Every lift system is equipped with an overspeed governor which acts as a device to stop or halt the lift when it runs beyond the designated speed. This device is mostly found installed in a traction lift.

    5.3.1.4.3 Electric Motor Thelift motor machine used in MITEC is the KONE EcoDisc permanent magnet synchronous machine, which is used for both the gearless traction lifts and MRL lifts. Its assemblage comprises of a permanent magnet synchronous motor, together with a vector-controlled drive system and energy regeneration options, providing the highest total efficiency and minimizing both mechanical and electrical losses when compared to traditional products. 5.3.1.4.4 Sheave The drive sheave or also known as the traction sheave, is described comprising of a metal sheave body or pulley fixed to an electric motor and having a novel cable groove liner around the circumference. The sheave grips the hoist ropes, so when the sheave is rotated, the ropes move too thus hoisting the lift car or counterweight.

    5.3.1.4.5 Counterweight The counterweightacts as an opposite to the load by exerting an almost equal opposite force. Its main purpose is to provide balance and stability when the lift is in motion, also optimizing the efficiency of lifting loads which helps to save energy. The counterweight can be found located in the hoistway which hangs on the others side of the sheave. 5.3.1.4.6 Guide Rail Both the counterweight and lift car travel along the guide rails along the sides of the lift shaft. Its purpose is to prevent the counterweight and lift car from swaying back and forth when in motion, and also work as a breaking rail with safety measures to stop the car during an emergency.

    5.3.1.4.7 Lift Buffer Thelift buffer can be usually found at the bottom of the lift shaft. Its purpose is to stop or halt the descending travel of the lift car or counterweight when it goes beyond its normal limit. This component is essential so as to reduce the injury suffered by users during an emergency fall. 5.3.1.4.8 Suspension Rope Suspension (hoist) rope (cable) is a device used to lift or lower a load, represented by steel wire ropes which act as suspension means for the car and counterweight. These are usually used on traction type lifts, attached to the crosshead and extending up into the lift motor room looping over the sheave on the motor then down to the counterweights.

    5.3.1.5.3 Travelling Cable Thetravelling cable is a vital link between the lift car and controller. In conventional elevators, all power transmission to the lift car and signal information is transmitted through the traveling cable. 5.3.1.5.4 Compensation Rope A compensating rope is a welded-link or plastic-coated chain, used to counterbalance the weight of the hoist ropes when it reaches a certain length that may tilt the balance of the car instead. This allows an equal load distribution on the drive sheave and motor, regardless of the car's position in the hoistway. One end of the chain is fastened to the bottom of the sling and the other end is attached to the bottom of the counterweight frame.

    5.3.1.5.4 Landing Door Thelanding door, or also known as hoistway doors, refers to the door that is visible from each floor of the building. These doors are usually automatically opened or closed by electric motors, but during emergency cases it can be manually opened as well. Safety devices are placed at each landing to prevent inadvertent landing door openings and prevent the lift car from moving unless it is in a locked position. The difference between the car door and landing door is that the car door is a part of the lift car itself, hence travels throughout within the hoistway; whereas the landing door are fixed to each landing floor nd is a part of the building itself. The type of landing door used in MITEC is the automatic door type, which has a central opening door comprising of two power-operated panels that part simultaneously with a fluid motion. 5.3.1.6 Interior of Lift Car 5.3.1.6.1 Car Wall Folded steel panels are used to enclose the lift car, along with the car floor and car ceiling that will be shown later. In MITEC, the normal passenger lift car walls are lined with stainless steel material whereas the glass lift has car walls made of glass panels.

    5.3.1.6.2 Car Floor Thefloor size ought to have the same dimensions as the lift car in terms of width and depth. The car floor must have sufficient mechanical strength capacity to withstand forces that are applied during normal operations, safety gear operation and impact of car to its spring buffers. There are two types of floor finish covers for lifts in MITEC. The passenger lifts have a marble stone finish whereas the freight lifts and fire lifts have a rubber finish. 5.3.1.6.3 Car Ceiling The car ceiling is designed to be able to withstand the weight of two people during maintenance operation without permanent deformation. It is also to mount the emergency trap door, blower fan and balustrade. Lighting fixtures are also mounted onto the car ceiling to provide lighting and improve the spatial experience when using the lift.

    5.3.1.7.2 Floor Designator Thefloor designator is placed on the wall adjacent to the lifts in the lift lobby, indicating the floor level that the passenger is currently on. In MITEC, a fire escape plan is placed underneath the floor designator. 5.3.1.8 Safety Features of Lift The lift transportation system is designed with many layers of safety features to ensure the utmost safety of its passengers, hence is also considered one of the safest mode of transportation in the market. Each lift system component are designed with integration of safety features, and this is applicable to the lifts found in MITEC as well. When an emergency arises, the alarm bells go off and the fire control room will swiftly verify the occurrence of a fire. Once confirmed, the standard lifts will immediately be overridden and move to park at the ground floor to allow passengers within to evacuate to the assembly point while the main power supply is disabled. At the same time, the fireman’s lift is manually activated using the fireman’s lift switch by the firemen or authorised personnel for evacuation or fire fighting purposes. As the main power supply had been earlier disabled, the fire lift is powered by a backup generator.

    5.3.1.8.1 Apron A carapron or also known as toe guard is a vertical protective board installed at the bottom of lift cars. This guard protects the passengers from being exposed to the open hoistway beneath the car if the doors are opened when it is not at the landing. 5.3.1.8.2 Safety Door Edge The car safety door edge functions to reverse the direction of door operation if a person or object is hit by the closing doors. There are also various other door-safety systems, for example a multi-beam door sensor that uses photoelectric beams or safety ray to detect people or objects. 5.4 Conclusion In MITEC, we can see the use of both escalators and lifts to provide vertical circulation, with sufficient numbers of these around the whole building to accommodate the large amount of passenger flow during peak hours or time. In terms of the mechanical transportation models, MITEC uses the latest technology by KONE which ensures the maximum quality of performance of the transportation system for its users. The mechanical transportation services provided are also in compliance with the requirements as stated in UBBL 1984, under section 124 for providence of lifts and under section 153, 154, 155 and 229 for fire safety features. Due to the mechanical transportation system in MITEC being subjected to constant heavy usage, proper maintenance of these services must be carried out frequently to ensure that they are in good condition to be used safely to transport passengers and goods.
